7a29abc7ee feat: run a workspace handler when a variable's value expires (#10837)
* feat: run a workspace handler when a secret variable expires

Secret variables gain an optional `value_expires_at`, and a workspace can point
at a script or flow to run once that date passes, so a rotation is driven by the
platform instead of tracked out of band.

The secret never leaves the database. The sweep selects the path, description and
expiry and nothing else, so the handler is given a reference to rotate rather than
a value to handle. Job results are stored in cleartext and shown in Runs, which is
what makes that a boundary rather than a preference; a test asserts the job's args
never contain the value.

Each row is claimed by writing `expiration_dispatched_for` in the same transaction
as the push, so a failed push un-claims it and a lost race claims nothing. Moving
the date re-arms the row; re-saving the same date does not. A pass takes at most
100 rows under a transaction-scoped advisory lock, and orders so that one broken
workspace cannot starve the rest.

Dispatch runs as `g/variable_expiration_handler`, exempt from the CE group limit
and from non-premium exec metering the way the error and schedule handlers already
are. A handler that keeps failing backs off and raises a critical alert instead of
retrying every pass, and the back-off ends when the handler is repointed.

The expiry travels with the variable through workspace clone, tarball export and
workspace comparison. The dispatch marker deliberately does not, so a fork re-arms
on its own copy.

* feat(frontend): expose variable value expiration in the UI

The variable drawer takes an optional expiry on a secret value, and the variables
list badges it, turning red once the date has passed. A workspace settings tab
picks the handler, its extra args, and whether variables under `u/` are skipped.

That mute flag is stored inside the handler setting, so the toggle stays disabled
until a handler is picked: saving it on its own would clear the setting it lives
in and still report success.

The expiry is carried as a tri-state through the draft deploy and copilot paths —
absent leaves the remote value alone, an explicit null clears it — so deploying a
draft cannot silently drop a date someone set elsewhere.

The settings tab names the one case where the configured identity does not apply:
a handler script carrying `on_behalf_of` runs as that user rather than as
`g/variable_expiration_handler`, which matters because the same tab asks the admin
to grant that group write access to the variables it rotates.

* feat(cli): sync variable expiry and the workspace expiration handler

`wmill sync` carries `value_expires_at` on variables in both directions, and
pushes the workspace handler alongside the error and success handlers in the
grouped settings format. Dropping the key from a variable's yaml clears the
remote expiry, so the file stays canonical rather than accumulating fields that
can only ever be added.

The handler follows the same rule, with the caveat recorded where the type is
declared: an omitted handler only reaches the clear when some other setting
differs, because the push short-circuits on a comparison that walks the local
object's keys and so never sees a missing one. That gate is shared with the two
existing handlers and is left as it is here.

* fix(frontend): open the variable expiration handler template in a new tab

The "Create a handler" button hands its script template to /scripts/add through
the URL hash, which `load` reads from `window.location`. A client-side navigation
leaves the previous page's hash in place, so the payload was dropped and the
editor opened on the default template at a `u/` path. `target="_blank"` forces a
full page load, matching the success handler's "Create from template" button.

* fix(frontend): make the variable expiry field state its own status

The expiry field rendered a DateTimeInput whose time defaults to 12:00 when it
holds no value, so a variable with no expiry looked like one already configured,
and "cleared" looked identical to "never set". Setting an expiry is optional, so
the field has to say which it is.

Rebuild it on the shape ScriptAdvancedSettings already uses for Timeout, Cache and
Concurrency limits: a toggle whose checked state is the stored value being present,
seeding a date on enable rather than revealing an empty picker, with the input
under its own label. Drop `clearable` with it, so the toggle is the single way to
mean "no expiry" instead of competing with an X.

Stop the surrounding copy promising a run that may not happen. A handler is only
dispatched if the workspace has one configured and does not skip u/ paths, so the
list tooltip now states the date alone, and the form hedges both conditions,
naming the u/ mute only on personal paths where it can apply.

Also anchor the mute toggle's tooltip: Popover's trigger is a span around a
block-level label, which stretched to the full width of its SettingCard and left
the popup floating beside the card rather than under the control.

* fix(rust-client): initialize value_expires_at in the variable models

The generated `CreateVariable` / `EditVariable` structs gain the field from
openapi.yaml, and client.rs builds both with exhaustive literals.

* fix(frontend): drop extra_args when the variable expiration handler is cleared

Clearing the handler nulls the whole setting server-side, extra_args included,
but the tab kept its loaded copy. A handler picked afterwards without reloading
was persisted with the cleared one's arguments, which the tab does not display.

* feat: back the variable expiration handler's built-in Slack and Teams destinations

Backfills the Slack bot token grant for g/variable_expiration_handler, mirroring
20231016142659 for g/error_handler: the slack_bot folder's extra_perms is written
once at Slack connect and never refreshed, and disconnecting leaves the folder
behind, so workspaces that already connected Slack cannot pick the grant up from
the creation-time list alone.

Adds run_variable_expiration_test_job so an admin can exercise the handler on
demand rather than waiting for a real expiry, which may be months away. It goes
through push_variable_expiration_handler so the test run proves what matters:
the handler resolves, and the group can read what it needs, under the same
identity and argument shape the sweep uses.

Also covers extra_args on the edit endpoint, which the settings tab now writes
for the built-ins' channel. The endpoint rebuilds the setting from the request,
so an omitted extra_args erases it.

* feat(frontend): offer Slack and Teams as variable expiration handlers

Gives the variable expiration tab the same no-code destinations the workspace
error handler has, so "tell #ops before this credential expires" no longer
requires writing a script.

A sibling component rather than a fourth mode of ErrorOrRecoveryHandler: that
one is shared with the workspace error handler and the three schedule handlers,
and its stripped-args list, hub path suffixes and Email tab are all
error-shaped. This reuses the pieces that are already generic
(SlackConnectionStatus, TeamsConnectionStatus, ChannelSelector, ScriptPicker,
SchemaForm) and leaves those five call sites untouched.

extra_args stops being an API/CLI-only escape hatch now that the built-ins write
their channel into it, so it joins the unsaved-changes comparison and the
discard path, normalised through the existing helper that drops the two
auto-managed keys.

The two hub ids are placeholders until the scripts are pushed to the hub.

* fix(frontend): scope the handler identity notice to the chosen destination

The notice told every admin to grant g/variable_expiration_handler write access
to the variables it rotates. That is right for a custom handler and wrong for
the built-ins, which only post a message and are granted the Slack bot token by
migration. Following it for a Slack handler would hand a group write access to
the workspace's secrets for no reason.

* feat(frontend): flag the Slack and Teams handlers as EE

Connecting a workspace to Slack or Teams is EE-only (oauth2_oss.rs returns
"Slack only available on enterprise"), so on CE those two tabs can never be
completed. Says so up front, the way the error/success handler tab does,
instead of leaving the user at a "not connected" badge with no working path.

Only on those two tabs: a custom script or flow handler is CE.

Drops the "Connect Slack first" alert, now that the banner and the connection
badge above it already say it twice.

* chore(backend): regenerate the sqlx cache after the merge

The merged workspace_settings column list in change_workspace_id is a new
query text, so it needs a new cached entry. Drops the two pre-merge entries
it supersedes; both had been left with conflict markers by the merge, since
rename/rename markers are eight characters and escape the usual scan.

* fix(frontend): disable the Slack and Teams handler controls without a license

Matches the workspace error handler, which greys out its built-in destinations
and hides the test button on an unlicensed instance. The custom destination stays
editable: unlike the error handler, the variable expiration handler itself is not
an EE feature.

* feat: record which destination a variable expiration handler uses

handler_configured now counts slack, teams, custom or cleared instead of
set or cleared, so usage shows whether the built-in destinations are picked.
