feat(projects): bring residential-project detail to parity with listings (4 phases)

Phase 1 — live POI + neighborhood score on project detail
- du-an-detail-client fetches `/analytics/pois/nearby` + `/analytics/neighborhoods/:district/score`
- Falls back to admin-entered `project.pois` / `neighborhoodScores` when endpoint returns nothing
- Adds total-score badge next to the radar chart (matches listings)

Phase 2 — project personas derivation (`lib/project-personas.ts`)
- Derives 8 personas from project-specific signals: property-type mix, amenity keywords,
  developer reputation, completion timing, status, live score + POIs
- Merges admin-authored `suitableFor` chips (badged "Chủ đầu tư chọn") with derived chips
- `composeWhyThisProject()` narrative used as fallback when admin hasn't authored one;
  badged "Tự động tổng hợp" so users know it's derived

Phase 3 — AI advisor for projects
- Extract shared Anthropic transport + JSON parsers to
  `analytics/application/queries/_shared/ai-json-client.ts` (dual auth: x-api-key +
  Bearer for proxy gateways)
- Refactor `GetListingAiAdviceHandler` to use the shared client
- New `GetProjectAiAdviceHandler` (CQRS) pulls project detail + optional POIs + score,
  builds project-flavored prompt, returns `{ advice: { summary, pros, cons, suitableFor } }`.
  No valuation block — project price is a range, not a single unit.
- `POST /analytics/projects/:id/ai-advice` endpoint (JWT-guarded)
- `ErrorCode.PROJECT_NOT_FOUND` added
- Frontend: `ProjectAiAdviceCard` mirrors listings card minus valuation, with loading /
  not-configured (503) / error states; dedupes AI-suggested personas against existing chips

Phase 4 — Mapbox LocationPicker in project create form
- New project page now renders `<LocationPicker>` with Vietnam-scoped geocoder; click /
  drag / search autofills lat+lng and (when empty) address/ward/district/city
- Edit page notes location immutability — backend `UpdateProjectCommand` does not yet
  accept lat/lng/address mutations (follow-up needed to enable editing coords)
