feat(api): collapse Slack, portal, and jobs onto Fargate (PLAT-216) (#259)

* feat(api): collapse Slack, portal, and jobs onto Fargate (PLAT-216) Move HTTP and scheduled work onto one always-on Flask task so after-hours loses Lambda cold start without changing the Cognito or roster contracts. * fix(portal-api): keep CORS headers on unexpected 500s Portal SPA error handling needs Access-Control-Allow-Origin even when DynamoDB or other internals fail, otherwise the browser hides the 500. * fix(api): retarget holidays per account and ship App Home changelog (PLAT-216) * fix(iam): list ECS tasks and fail closed on non-prod Paychex (PLAT-216) * fix(portal-api): serve portal JSON with an explicit JSON content type

+3. Instant cut: Slack Request URL, Paychex `AFTERHOURS_BASE_URL`, portal
+   `VITE_SHIFTS_API_BASE` → `https://afterhours.seahaven.com` (dev hostname in
+   portal-dev). Smoke `/oncall`, roster PUT/DELETE, `GET /api/shifts`, one
+   holiday GetSchedule, ring job.
+4. Set `ecs_schedules_enabled=true` and keep `schedules_enabled=false`. Confirm
+   no 3CX writers remain on Lambda.
+5. After smoke, remove API Gateway, the eight Lambdas, zip packaging, and
+   Lambda alarms in a follow-up apply. ALB 5xx/latency and unhealthy-host
+   alarms stay.

 A holiday is a day-only shift (08:00-17:00 ET), one HOLIDAY record per date.
 At 08:00 this Lambda is invoked with ``{"action": "activate", "date": ...}`` and
 at 17:00 with ``{"action": "deactivate", ...}``.
-
-Activate:
-  * Capture both IVR 800 routes (key-0 and no-input/timeout) into
-    ``CONFIG.captured_ivr_routes`` — but only if they are NOT already pointed at
-    the holiday queue (so a re-run never overwrites the real originals).
-  * Set queue 802's agents to the holiday's assignees, or ``[FALLBACK_EXTENSION]``
-    ("100") when no slots are filled. Membership is set ONCE here.
-  * Repoint BOTH IVR 800 routes to the holiday queue (802).
-  * Mark the holiday ``activated = True``.
-  Idempotent: no-op if the record is gone or already activated.
-
-Deactivate:
-  * Restore both IVR routes from ``CONFIG.captured_ivr_routes`` — only the routes
-    that currently point at the queue are reverted (defensive against manual
-    changes); clear the captured routes afterwards.
-  * Clear queue 802's agents.
-  * Mark the holiday ``activated = False``.
