34de8bc06d feat: slack agents through a workspace's own slack app (#11912)
* feat: let Slack agents answer through a workspace's own Slack app, with signing secrets set from the UI

The instance Slack app's signing secret can be set in its OAuth setting as well as
SLACK_SIGNING_SECRET, and a workspace's own Slack app takes its own in the workspace
settings. Each secret only vouches for the workspaces connected through its app, so
/windmill keeps working for a workspace whose app has none set.

* fix: keep Slack signing secrets out of logs and verify an own app without a secret with the instance's

* fix: report a workspace app's own signing secret in the Slack agents status

* fix: check Slack approval callbacks against the instance signing secret only

An approval can be sent through any Slack resource, so the team's workspace
connections do not tell which app signed its callback.

* fix: share the Slack app setup instructions and require the signing secret for agents

* fix: tidy the Slack signing secret copy and show a set secret as masked

* fix: check a workspace app only against its own signing secret, and approvals against their workspace's

* fix: accept a Slack approval signed by the workspace's app or the instance's

* fix: check Slack's signature on approvals only when sent through the workspace's Slack connection

Any other Slack resource may belong to any Slack app, so its callbacks rest
on the payload HMAC alone.

* fix: address review findings on Slack signature checks and the signing secret field

- reject Slack signatures older than five minutes, so a captured request cannot be replayed
- let a reachable workspace's command script take a message before another workspace's help reply
- remove a saved workspace signing secret from its field: the button reads Remove when it is empty
- set the signing secret on connect only when one was entered
- tell non-admins who can set the signing secret

* fix: keep SLACK_SIGNING_SECRET for workspace apps without a secret, and route a verified request only to its workspaces

- a workspace on its own app with no secret of its own is checked against SLACK_SIGNING_SECRET,
  which may hold that app's secret from before workspaces had one; the instance setting's secret
  still never applies to it
- once a secret verifies a request, only the workspaces it verified take it, command scripts
  included: it proves which app sent the request
- compute the replay window with abs_diff, which cannot overflow
