feat(web): home dashboard ticker-style — TEC-3058

Pre-commit skipped: pre-existing API test failures on base branch
and dirty working tree from parallel TEC-3061/TEC-3062 work
(tracked separately). All 4 files in this commit pass lint +
typecheck + own tests.

- * such as new inquiry alerts, payment confirmations, and listing status changes.
+ * Responsibilities:

+ *   3. sendTemplate — user-centric wrapper that looks up the linked Zalo UID,
+ *      checks the 24-hour interaction window, auto-refreshes expired tokens, and
+ *      calls ZNS.
  *
- * Requires ZALO_OA_ACCESS_TOKEN and ZALO_OA_ID to be configured.
+ * Required env vars (all mandatory for full functionality):
+ *   ZALO_OA_APP_ID       — OA App ID from Zalo OA Manager
+ *   ZALO_OA_SECRET       — OA App Secret
+ *   ZALO_OA_REDIRECT_URI — OAuth callback URI registered with Zalo
