Phase 4 §2 + §1/§4: OnboardingIntent post-OTP routing + test naming + register-screen overflow

Spec §2 (flow_customer.mermaid) routes post-OTP based on user-lookup +
has_transacted, but the implementation previously dumped every OTP
success on /home. Introduce `OnboardingIntent` provider: set to
`onboarding` by routeForVerifChoice's verified branch (the "aku mau
curhat" transaction journey), set to `recover` by SHome1st's masuk →
banner. Router redirect on AuthAuthenticatedData+isAuthRoute consumes it:
`onboarding` → /payment/entry (dispatches S6 paywall vs PickMethod via
first_session_discount.eligible); `recover` → /home. Intent is reset in
/payment/entry's initState so subsequent masuk → flows don't inherit it.

auth_notifier.verifyOtp uses .copyWithPrevious on AsyncError so
valueOrNull retains AuthOtpSentData/AuthAnonymousData through OTP
failures — required for the OTP-blocked recovery path
(/onboarding/anon/method → /payment/method-pick) to clear the global
redirect without bouncing to /home. Router also extends the
isAuthRoute/isOnboardingFlow carve-out to AuthOtpSentData.

Maestro tests adopt `ts-<app>-<NN>-<MM>-<descriptor>.yaml` convention:
NN = mermaid section, MM = sub-flow index. New ts-customer-02-01..05
cover the §2 branches (verified brand-new → S6, existing-no-tx → S6,
existing-tx → method-pick, OTP-blocked → method-pick, anonymous first-
timer → method-pick); deferred 02-06/07/08/09 documented in
README_section_02.md. TS-07 → ts-customer-02-10 (masuk → recovery);
TS-01..06 → ts-customer-04-01..06 (§4 returning-user). Shared
onboarding_new_user_verified.yaml subflow extracted.

Register screen's body Column now uses LayoutBuilder + SingleChildScrollView
+ ConstrainedBox + IntrinsicHeight so the keyboard-open layout no
longer overflows by 1.3 px (verified visually).

Spec prose updated at flow_customer.mermaid §2 to describe the
intent-driven routing + login-vs-transaction divergence.

+# §2 — New-User Onboarding test plan
+
+Spec: [requirement/flow_customer.mermaid.md §2 + §2.1](../../../requirement/flow_customer.mermaid.md).
+
+Tests use the naming convention `ts-customer-<section>-<sub>-<description>.yaml`:
+- `<section>` — flow_customer.mermaid section number (`02` for §2 + §2.1).
+- `<sub>` — sub-flow index within the section.
+- `<description>` — snake_case summary of the branch under test.
+
+## Implemented
+
+| File | Branch (spec ref) | Expected destination |
+|---|---|---|
+| `ts-customer-02-01-verified_brand_new_to_s6_paywall.yaml` | §2 verified · UserLookup=no (brand-new) | `/payment/discount-paywall` (S6) |
+| `ts-customer-02-02-verified_existing_no_tx_to_s6_paywall.yaml` | §2 verified · existing customer · has_transacted=false | `/payment/discount-paywall` (S6) |
+| `ts-customer-02-03-verified_existing_transacted_to_method_pick.yaml` | §2 verified · existing customer · has_transacted=true | `/payment/method-pick` (PickMethod) |
+| `ts-customer-02-04-otp_blocked_fallback_anonymous_to_method_pick.yaml` | §2 verified · OTPok="too many retries" → OTPBlock → fallback | `/payment/method-pick` (PickMethod) |
+| `ts-customer-02-05-anonymous_first_timer_to_method_pick.yaml` | §2 anonymous · USPGateB=first-timer → USPb | `/payment/method-pick` (PickMethod) |
+| `ts-customer-02-10-recover_via_masuk_existing_user_to_home.yaml` | SHome1st "masuk →" recover · existing identified user | `/home` (returning view) |
+
+The shared verified-onboarding prelude lives at
+[`../subflows/onboarding_new_user_verified.yaml`](../subflows/onboarding_new_user_verified.yaml).
+
+## Deferred (not yet implemented — see reasons)
+
+### `ts-customer-02-06` — anonymous · USP already seen → PickMethod directly
+**Branch:** §2 anonymous · USPGateB=seen → skip USP → PickMethod.
+
+**Why deferred:** verifying the seen=true skip path literally requires the
+user to reach `VerifChoiceSheet` while local `flutter.usp_seen=true` AND
+auth state is fresh (`AuthInitialData`, no anon customer). Maestro's
+`launchApp clearState:true` wipes both `SharedPreferences` and
+`FlutterSecureStorage` together — there's no built-in way to clear ONLY
+secure storage between passes. A two-pass test that runs USP once then
+relaunches preserves both prefs and the anonymous session, so Pass 2 lands
+on `SHomeReturning` instead of `SHome1st`, bypassing VerifChoiceSheet.
+
+**Possible future approach:** add a shell-level pre-test step that runs
+`adb shell run-as <pkg> rm shared_prefs/FlutterSecureStorage*.xml` and
+preserves `FlutterSharedPreferences.xml`, then invoke maestro. Requires a
+wrapper script or a maestro extension that can call adb.
+
+### `ts-customer-02-07` — §2.1 5.1 anon transact → OTP new phone → upgrade in place
+### `ts-customer-02-08` — §2.1 5.2 anon transact → OTP existing phone → merge (existing has_transacted=true)
+### `ts-customer-02-09` — §2.1 5.2 merge · existing has_transacted=false
+
+**Branch:** §2.1 anonymous → existing-user merge sub-flow.
+
+**Why deferred:** §2.1's prereq is "anonymous customer has completed at
+least one transaction". The app derives `has_transacted` from
+`chat_sessions` rows, and the auth flow ties customer identity to the
+device's `FlutterSecureStorage` refresh token. Reproducing the prereq in
+Maestro requires either:
+
+1. Driving the app UI all the way through anonymous transaction → payment
+   confirm → pairing → chat → end-session (a full §3 + §5 + §6 traversal),
+   then triggering OTP from the SHomeReturning state. The SHomeReturning
+   "curhat sama bestie baru" CTA bypasses `VerifChoiceSheet` entirely, so
+   the only OTP entry point from this state is the SHome1st "masuk →"
+   banner — which is only shown on SHome1st (no identity), not on
+   SHomeReturning.
+
+2. Pre-seeding a customer + chat_session in the DB *and* injecting the
+   corresponding refresh token into the device's FlutterSecureStorage so
+   the app boots as that anonymous-with-transactions customer. Maestro
+   doesn't expose adb shell exec, so this requires a wrapper script.
+
+In practice, the §2.1 merge logic is more naturally covered by **backend
+integration tests** against `resolveCustomerForIdentity` in
+`backend/src/services/auth.service.js` — the app-side behavior after
+re-login is the same `/home` landing (login intent) tested by 02-10. The
+merge state is a backend invariant, not a UI invariant.
+
+## Behavior notes
+
+- §2 verified branches route post-OTP via `/payment/entry`, which then
+  dispatches based on the backend's `first_session_discount.eligible`
+  (see `backend/src/services/pricing.service.js::isCustomerEligibleForFirstSessionDiscount`).
+  This handles both "brand-new" and "existing-but-never-paid" with a
+  single check.
+- The `OnboardingIntent` provider (added 2026-05-18 with the §2 fix)
+  distinguishes transaction-CTA entries (`onboarding`) from login-recover
+  entries (`recover`). Set at `verif_choice_sheet.dart::routeForVerifChoice`
+  (verified branch) and at `home_screen.dart::_LoginRecoverBanner`
+  (masuk →). Consumed by `router.dart`'s post-OTP redirect.
+- `auth_notifier.dart::verifyOtp` uses `.copyWithPrevious(previous)` when
+  setting `AsyncError`, so `valueOrNull` retains the prior
+  `AuthOtpSentData` / `AuthAnonymousData` through the OTP-blocked popup
+  → fallback path.

+> **Implementation (2026-05-18):** post-OTP routing is driven by an
+> `onboardingIntentProvider` (`client_app/lib/core/auth/onboarding_intent_provider.dart`)
+> that's set to `OnboardingIntent.onboarding` by `routeForVerifChoice`
+> (verified branch in `verif_choice_sheet.dart`) and consumed by the
+> router redirect for `AuthAuthenticatedData` on any auth route. When the
+> intent is `onboarding`, the redirect returns `/payment/entry`; otherwise
+> (default `recover`, set by the masuk → handler) it returns `/home`.
+> `/payment/entry` then dispatches S6 vs PickMethod via the backend's
+> `first_session_discount.eligible` flag — which is computed as
+> "phone-verified AND no prior completed chat_sessions" in
+> `pricing.service.js::isCustomerEligibleForFirstSessionDiscount`. That
+> single check covers both "brand-new" and "existing-but-never-paid"
+> (UserLookup=no and UserLookup=yes+has_transacted=false in the mermaid
+> above).
+>
+> **Login-vs-transaction divergence:** the SHome1st "masuk →" login-recover
+> banner pushes `/auth/register` with intent left at `recover`, so its
+> post-OTP path lands on `/home` (the user expects to see their chat
+> history, not be thrown into payment). This is a deliberate departure
+> from a strict reading of the mermaid arrow, motivated by the user
+> directive that login-intent and transaction-intent entries should not
+> share the same landing zone. Maestro coverage:
