Phase 4 Stage 10 backend: Chat-tab feeds (pending payments + cursor history)

Backend half of Stage 10 — the new Chat tab in the customer app that replaces /chat/history with a 3-sub-tab list (Aktif / Pembayaran / Selesai). - New GET /api/client/payment-sessions/pending — returns the customer's pending initial + extension payment sessions. Filter is status='pending' AND expires_at > NOW(). Mitra info comes from session_extensions → chat_sessions for extension rows, payment_sessions.targeted_mitra_id for targeted-curhat-lagi initial rows. TTL reuses the existing payment_session_timeout_minutes app_config row (default 20m) — no new config row needed since payment is still mocked. - getCustomerHistory migrated from offset (page/limit) to cursor pagination. Cursor is base64url(`<endedAtIso>|<id>`) with id-tiebreak in ORDER BY so rows with identical timestamps don't duplicate or skip across pages. SELECT now JOINs payment_sessions to surface `mode` (chat/call) for the Selesai-row voice-call pill. - requirement/flow_customer.mermaid.md: new §7 Chat Tab subgraph + Figma cross-ref entry for SChatList. - requirement/phase4-customer-flow-plan.md: Stage 10 plan section. Also carries forward earlier uncommitted "Post-Stage-8 corrections" notes from the Stage 9 sweep (boot path / SHome1st / onboarding fixes). Tests: +7 for getCustomerPendingPayments (initial null mitra, targeted-mitra fill, extension-via-session JOIN, mixed-newest-first, expired excluded, non-pending excluded, customer scoping). +10 for cursor history (empty, exact-fit, multi-page walk, same-timestamp tiebreak, limit clamp, customer scoping, CLOSING+COMPLETED only).

+> **ESP screening removed (2026-05-12):** the S5 ESP multi-select chip
+> screen is retired from the spec. Both verified and anonymous branches
+> now go from `VerifChoiceSheet` straight to the `usp_seen?` gate. Any
+> ESP code still in `client_app` is now tech debt to retire — see
+> `TECH_DEBT.md`.
+>
+> **S5b USP is one-time-only (2026-05-12):** the USP screen now shows at
+> most once per user. Gating is driven by a `usp_seen` flag that lives in
+> two places:
+> - **Local (SharedPreferences):** the runtime gate. Set to `true` when the
+>   user dismisses the USP screen for the first time. Survives across
+>   sessions on the same device.
+> - **DB (`customers.usp_seen` column 🔴):** the cross-device source of truth.
+>   Written when the user account is created (post-OTP, after JWT issuance
+>   and `users` row insert) if local flag is already true, OR on any
+>   subsequent USP dismissal once an account exists. Read on login/relogin
+>   and hydrated back into local. "True wins" — if either side says seen,
+>   the gate is closed.
+>
+> Anonymous users with no account only have the local flag; if they later
+> upgrade to verified, account creation propagates the local flag to DB.
+> Returning verified users on a fresh device will see USP at most once on
+> that device (DB hydrate happens on login, after USP gate fires pre-OTP).
+> Business has accepted this edge case.
+>
 > **Anchor mismatch:** flow_customer.md numbers ESP/USP under
 > `5.1.2 Verification request (OTP)` for both branches, but Figma puts
 > `VerifChoiceSheet` *before* ESP. The mermaid above follows Figma; reconcile in
 > phase4 spec.
+>
+> **Post-OTP account lookup (added 2026-05-11):** the verified path is not
+> always "new user". After a successful OTP, the backend looks up the phone
+> number; if a row exists, the app overwrites the freshly-typed call_sign with
+> the stored one. Then `has_transacted` decides routing:
+> - `false` → S6 Paywall (Rp2.000 first-session) — user has an account but
+>   never converted.
+> - `true` → jump straight into `PickMethod` (the regular chat/voice +
+>   duration + payment flow). USPb is already skipped because USPGateA
+>   already evaluated pre-OTP on the verified branch.
+>
+> `has_transacted` is the persistent flag on the users table that flips the
+> first-time pricing off forever. Backend phone-lookup behaviour already
+> exists (see Phase 1 auto-link via phone); the app-side reconciliation +
+> `has_transacted` plumbing is the new work.
