frontend phase 4: catalog browse (Home A5) & nurse service builder (B7)

Light up the two faces of the configurable service catalog over a new cached
services/catalog domain (consumes the b5 contract; unlocks f6 search).

- services/catalog: types/keys/constants/apis(client+mock+seam)/hooks/index +
  names.ts. Categories & option groups are session-cached reference data
  (Infinity staleTime, like geography); variant mutations invalidate
  myVariantsLists() and setQueryData the edited row. Mock-primary
  (USE_CATALOG_MOCK), one-line swap; mock reproduces the 400 missing-required
  and (nurse,category,option-set) 409 duplicate rules.
- Customer Home (A5): greeting+avatar, search bar (navigates toward f6),
  data-driven category grid (loading/empty/error), patient nudge from the
  cached f2 query. Deferred /search placeholder stub.
- Nurse Services & prices (B7) at /nurse/services: offerings list (active vs
  deactivated, edit, soft-deactivate w/ confirm, reactivate, no delete) and a
  3-step variant builder (category -> required/optional options -> price+unit+
  duration). Required-group gate; Toman->IRR digit-string at the field
  boundary (no float); live unit-aware estimated total (never from price
  alone); editable auto display_name; inline 409 duplicate warning; locked
  category edit form.
- Shared, tested components: CategoryTile, PriceDisplay, VariantCard. Money
  util: tomanToRial + multiplyIrr (integer-safe) + tests.
- i18n: catalog/services/search namespaces + home additions + nav.services
  (both locales, in sync). Icons, routes (SEARCH, NURSE_SERVICES), nurse nav.

Gate: npm run check green; npm run test:ci green (147 tests, +18 across 4
suites); npm run build green with NEXT_PUBLIC_API_URL set.

Docs: client/CLAUDE.md (Project Structure, caching note, namespaces), STATUS,
for-backend REQ-010 (pagination param casing), phase report, mocks registry.
