Ho Ngoc Hai 3a9e44758c fix(web): unwrap CacheMetaInterceptor envelope + dev port migration + homepage diacritic
Several fixes discovered while smoke-testing the homepage under the new
port layout (web 3200 / api 3201) to avoid clashing with a sibling project:

- analytics-api: add `unwrap<T>()` helper for the `{ data, cacheMeta }`
  envelope the backend CacheMetaInterceptor appends to every
  `/analytics/*` response. Apply to all 9 analytics methods. Without this
  `data.activeCount` (etc.) were `undefined`, crashing KpiStrip with
  `TypeError: Cannot read properties of undefined (reading 'toLocaleString')`.
- public page: hard-coded `city = 'Ho Chi Minh'` returned 0 rows because
  the DB stores `'Hồ Chí Minh'` and the SQL filter is case-insensitive but
  not diacritic-insensitive. Use the accented spelling.
- use-analytics hooks: add `useAuthedAnalytics()` gate so unauthenticated
  visitors on public routes no longer fire 401s from analytics queries.
- next.config.js CSP: add localhost:3200/3201 (http + ws) to connect-src so
  the web origin can reach the relocated API. Without this fetches hit
  `TypeError: Failed to fetch` on login.
- .claude/launch.json + package.json: web → 3200, api → 3201 (was 3000/3001,
  conflicting with the sibling psyforge project also using 3000).
- Minor follow-ups from parallel QA work on this branch (analytics modules,
  notifications gateway, auth test fixtures, trending-areas handler + DTO
  + tests, a few E2E smoke specs).
