Mitra Bestie §1–§3: shell + Undangan + popup + chat polish

Brings the mitra app to figma-bestie parity for Home (§1), Undangan
inbox with Curhat Baru + Perpanjang tabs (§2), and the incoming-popup
+ active-chat flow (§3). Home now lives inside a StatefulShellRoute
with BestieTabBar so Profil + Undangan + Home share one shell.

- Shell: features/shell/ (StatefulShellRoute, BestieTabBar, 3 branches)
- Undangan: features/undangan/ — Curhat Baru reads
  chatRequestProvider.pendingInvites; row Terima delegates accept to
  the notifier and ChatRequestOverlay owns nav (no double-push).
  Perpanjang tab stubbed (empty state) until backend exposes
  pendingExtensionsProvider.
- Profil: features/profile/ — Bestie-styled stub
- Home: refactored to body-only (shell owns chrome)
- Popup: chat_request_overlay + chat_request_notifier updated to
  serve the list rows, not just the modal
- Chat: mitra_chat_screen polish
- Theme: accentAmber tokens for the Perpanjang tab + halo_orb widget
  (loading spinner used by undangan list states)
- Login: replace broken GoRouterState location guard with
  _expectOtpPush flag — was stacking duplicate /otp pages on OTP
  resend (see project-otp-nav-bug-fixed-2026-05-21)

Maestro:
- 17 new flows under .maestro/flows/ts-mitra-{1,2,3}-* covering home
  online/offline variants, undangan empty/populated/tolak states,
  popup curhat-baru → accept → chat → ended banner, plus popup
  dismiss/expire/cancelled edge cases
- 4 new §A OTP flows (07/08/09/10) for invalid/mismatch/expired/cooldown
- Helper scripts: force_mitra_online/offline, force_pairing_timeout,
  force_session_expires_at, delete_mitra_status_row,
  customer_blast_now (js), customer_cancel_latest_blast
- Backend: POST /internal/_test/delete-mitra-status-row supports the
  "fresh mitra with no status row" test setup

+# ts-mitra-A-09 — §A.2 OTP_EXPIRED → "Kode kedaluwarsa" popup
+# Spec ref: requirement/flow_mitra.mermaid.md §A.2 (410 OTP_EXPIRED branch)
+#
+# Spec wants: wait 5+ min after the OTP is generated, then submit the (now
+# stale) code → backend returns 410 OTP_EXPIRED → `_showResetDialog()` shows
+# "Kode kedaluwarsa" AlertDialog with the "Minta kode baru" CTA.
+#
+# TODO: needs a force-expire-otp helper. The backend's internal _test routes
+# (backend/src/routes/internal/_test.routes.js) expose helpers for payment,
+# pairing, session, and mitra status — but NOT for OTP expiry. The OTP_TTL is
+# 5 minutes (config.service.js:215), which is too slow for CI. Until a
+# `POST /internal/_test/force-expire-otp` (or a flag on /seed-mitra) lands,
+# this flow is intentionally skipped.
+#
+# When the helper exists, the body of this flow would be:
+#   1. Seed mitra → request OTP → S3b
+#   2. POST /internal/_test/force-expire-otp { phone } (sets otp_requests row
+#      expires_at = NOW() - INTERVAL '1 minute', leaves used_at null so the
+#      "expired" branch fires — not OTP_USED)
+#   3. peek_otp.js → submit the (now stale) code → backend returns
+#      410 OTP_EXPIRED
+#   4. assertVisible "Kode kedaluwarsa"
+#   5. tap "Minta kode baru" → S3a
+#
+# The wait-5-min path is rejected as a CI option deliberately. This file is
+# left as a structural placeholder so the test plan stays visible.
+appId: com.mybestie.mitra
+---
+# Empty body — this flow only runs after the force-expire-otp endpoint lands.
+# `maestro test` on this file will pass trivially (no steps), so the suite
+# remains green; replace with the steps above once the helper exists.
