frontend phase 2: onboarding & profiles — customer/patient, nurse profile & bank

Turns a logged-in user into a usable account, consuming the b3 identity-profiles
contract behind the services/{domain} seam.

Services (mock default true; real HTTP clients wired for a one-line flip):
- services/patients: rewritten to b3 PatientDto + client-augmented relation/conditions;
  full CRUD, optimistic soft-archive, cache-splice on create, age<->birthDate helper.
- services/profiles: customer + nurse profile get/upsert + avatar (404->null mapping).
- services/nurse: payout bank accounts + IBAN(Sheba) util + pending-only polling.

Screens: A3->A4 onboarding wizard, E1 patients list/CRUD, A5 home (first-login gate +
nudge), customer profile (no national-ID), nurse profile bootstrap (unverified
placeholder), nurse bank settings (pending/verified/mismatch + make-primary).

Shared composites (each tested): GenderToggle, ConditionChips, RelationSelect,
PatientForm, PatientCard, BankStatusPanel; reuses f0 StepperHeader/StatusChip/PhoneField.
Adds onboarding/home/profile/nurseProfile/bank i18n namespaces (both locales, in sync),
the --bal-primary-soft token, and nurse sidebar Profile + Bank entries.

Contract gaps filed: REQ-005 (patient relation/conditions), REQ-006 (avatar route),
REQ-007 (customer name/language). Gate: check + 112 tests + build all green.
