Vamsi Karthik R c3056cc720 test(alerts): E2E suite for email destinations and distribution lists (#13876)
Automated coverage for **email alert destinations and distribution
lists**, and unblocks the email tests that have been skipped since they
were written. **32 cases** — 27 active, 5 skipped regressions tracking
open defects (openobserve/o2-enterprise#2471).

**The unblocking.** The two skipped tests said *"the test environment
does not have email infrastructure set up"*. That over-stated it:
creating, editing, validating and deleting an email destination needs
SMTP switched **on**, and never reads a mailbox. Only delivery
assertions do. The suite is tiered on that:

| Tier | Needs | Cases |
|---|---|---|
| A | SMTP enabled | 24 |
| B | a readable sink | 2 |
| C | an alias that fans out | 1 |

**Tests**
- `Alerts/dl-email-destinations.spec.js` (32) — the DL half (alias
accepted, addressed, fanned out) and the recipient-list half, where our
code actually runs: splitting/trimming/lowercasing, the org-membership
gate, edit round-trips, add/remove/delete, both form paradigms (prebuilt
free-text vs the custom path's org-user picker), template auto-attach,
duplicate names, cancel, type-switching, keyboard, dark mode at 420px.
- `utils/mail-sink.js` — pluggable sink: Mailpit, a Mailinator inbox, or
a clean skip with a stated reason.
- `utils/o2-api.js` — storage is asserted from the API, never the form
field: an input can echo what you typed while the stored value differs.
- `scripts/dl-relay.js` — SMTP relay that expands one alias into
per-member deliveries, so fan-out runs with no external provider. Same
pattern as the in-test HTTP receiver in
`alerts-content-templates.spec.js`.
- `alertDestinationsPage.js` — +17 methods; the spec carries zero raw
locators.

**Replaces, without losing coverage.** The two skipped tests in
`alerts-destinations-prebuilt.spec.js` are removed for a pointer mapping
their intent to its new home: create (`D-01`), edit-add (`D-07`),
edit-remove (`ML-08`), delete (`UI-12`), format validation (`UI-02`).
Three of those did not exist before. That file now has no skips.

**CI.** `ZO_SMTP_ENABLED: true` was already set in `playwright.yml` but
had no host or port, so it fell back to `localhost:25` where nothing
listens — destinations could be **saved** while every **send** failed
silently. The workflow now starts Mailpit and a DL relay as static
binaries before the app (no Docker-in-Docker on these runners) and
points `ZO_SMTP_*` at them.

All three tiers run with no secrets and no egress. Verified in the CI
topology: **27 passed, 5 skipped**, `D-02` confirmed reaching all three
member mailboxes.

**Behaviour.** Self-cleaning via the `auto_dest_dl_*` prefix
`cleanup.spec.js` already sweeps, plus an API `afterAll`. `mode:
'parallel'` — each test owns its fixtures.

**Findings** are filed in openobserve/o2-enterprise#2471, not fixed
here. Two P1s: the *"Show matching rows"* toggle is ignored so log rows
are always embedded, and a user removed from the org keeps receiving
alerts while the destination can no longer be saved. The regression
tests for each are in this PR, skipped until the fix lands.

**Paired ENT PR: openobserve/o2-enterprise#2472.** ENT's workflow sets
`ZO_SMTP_ENABLED: false`, so without it the suite skips all 27 cases
there. The shard matrix needs no ENT change — ENT builds it from this
repo's `ci_matrix.json` plus its overlay, so the new spec is picked up
automatically. Merge the two together: this one alone leaves enterprise
with no email coverage.
