Promotes the customer-side chat WebSocket to active-session-scoped (driven
by a new `activeSessionProvider`) so home reflects session state in real
time without a per-screen connection. Backend now auto-completes sessions
left in `closing` after a 5-minute grace window so abandoned goodbye flows
don't leave the customer's home permanently locked.
Customer:
- New `activeSessionProvider` (replaces `unread_notifier`) — single source
of truth for the active session + unread count; polled every 15s.
- Chat WS lifecycle moved to `main.dart` listener on activeSessionProvider.
Chat screen joins via `connectIfNotConnected`; the new
`refreshSessionStatus` reconciles flags from the server when re-entering
an already-connected session (covers missed `sessionClosing`/`sessionExpired`
WS events).
- Home filters `closing` from the "Sesi Aktif" CTA so a session pending
goodbye doesn't block "Mulai Curhat".
- Timer-expired UX is a non-dismissible modal (Tutup / Perpanjang) instead
of an inline bar.
- Early-end goodbye composer gets an amber "Sesi telah ditutup oleh Bestie"
banner. Goodbye TextEditingController lifted to state so focus changes
no longer wipe the message.
- Closure provider reset on chat_screen mount to avoid stale
`ClosureCompleteData` from a previous session leaking into a new view.
- Chat history now lists `closing` sessions with a "Belum ditutup" badge
that routes to the live chat (goodbye composer) instead of the transcript.
Mitra:
- Same goodbye-controller fix as customer.
- Same chat-history badge + routing for `closing` items.
Backend:
- New `EndedBy.SYSTEM_AUTO_CLOSE` constant.
- `startClosureGraceTimer` extracted in `session-timer.service.js`; wired
in from `closure.initiateEarlyEnd`, `extension.rejectExtension`, and
`extension.handleExtensionTimeout`. Cancelled when customer submits
goodbye.
- Restart recovery (`restoreActiveTimers`) re-arms grace timers and stamps
any orphaned `closing` rows with `system_auto_close`.
- `getCustomerHistory` / `getMitraHistory` include `closing` alongside
`completed`; ordering uses `COALESCE(ended_at, created_at)`.
Removed: dead `session_active_screen.dart` (no router entry).
