feat: add P0/P1/P2 features + Swagger enrichment for MVP completeness

Closes four gaps the Swagger audit flagged as blocking a full MVP demo,
plus a general documentation pass.

P0 — Forgot/Reset password (auth)
- POST /auth/forgot-password (anti-enumeration: always 200)
- POST /auth/reset-password
- Reuses the Redis-OTP pattern from email/phone change; new key prefix
  auth:password_reset_otp with 15-min TTL.
- Emits PasswordResetRequestedEvent; new listener in notifications
  dispatches the existing password.reset email template (otp +
  expiryMinutes variables already in template.service.ts).
- UserEntity gains changePassword(HashedPassword) domain method; reset
  also revokes all refresh tokens for the user.

P0 — Favorites module
- New SavedListing Prisma model (unique(userId, listingId)) with User
  and Listing back-relations; schema pushed via db push since the
  remote DB was out of sync with migration history.
- New apps/api/src/modules/favorites/ module following the reviews
  module's shape (DDD/CQRS: domain repo + Prisma impl + 2 commands
  + 2 queries + controller).
- POST /favorites/:listingId, DELETE /favorites/:listingId,
  GET /favorites (paginated), GET /favorites/:listingId/check. All
  guarded by JwtAuthGuard.
- FavoritesModule wired into AppModule.

P1 — Resend OTP (auth)
- POST /auth/resend-otp for EMAIL_CHANGE | PHONE_CHANGE. Reads the
  pending OTP payload out of Redis and re-emits the original event
  without minting a new code, so TTL semantics stay intact. Password
  reset resend is done by re-POSTing /auth/forgot-password and is
  deliberately not in this enum.

P1 — Agent self-upgrade (agents)
- POST /agents/me/upgrade lets a BUYER/SELLER convert to AGENT. Creates
  an Agent row (isVerified=false) and flips User.role in one
  $transaction. Rejects if already AGENT/ADMIN or if an Agent row
  already exists.

P2 — Swagger enrichment
- @ApiConsumes('multipart/form-data') + body schema on listings media
  upload.
- GET /subscriptions/quota/:metric now enumerates the real metric
  values from METRIC_TO_PLAN_FIELD.
- POST /avm/batch and /analytics/valuation/batch document the max=50
  batch size from their DTO's @ArrayMaxSize.
- GET /admin/dashboard gains a realistic response example schema.
- Admin-gated endpoints in projects/transfer/industrial gain concrete
  400/401/403/404 responses.

Swagger endpoint count: 170 → 178. Typecheck clean.

+## 10. RISKS & ISSUES
+
+### Critical Issues
+| Issue | Severity | Status | Mitigation |
+|-------|----------|--------|-----------|
+| **No field-level PII encryption** | 🔴 HIGH | Open | Implement cell-level encryption (phone, email) |
+| **MFA not enforced for agents/admins** | 🔴 HIGH | Open | Require TOTP on first admin login |
+| **Web unit test coverage < 10%** | 🟡 MEDIUM | Open | Target 50+ unit tests + 60% coverage |
+| **Per-endpoint rate limiting missing** | 🟡 MEDIUM | Open | Fine-grained rate limits (register 3/min, login 5/min) |
+| **Load test baseline outdated** | 🟡 MEDIUM | Open | Re-establish post-industrial-avm features |
+| **Industrial AVM model may be overfitting** | 🟡 MEDIUM | Open | Collect 1000+ industrial property records |
+
+### Technical Debt
+| Item | Effort | Impact | Action |
+|------|--------|--------|--------|
+| Refactor large modules (search, admin) | Medium | Low | Split into sub-modules for clarity |
+| Reduce Prisma query duplication | Medium | Medium | Extract common WHERE clauses |
+| Upgrade Node.js to 24 LTS | Small | Medium | Update package.json + tests |
+| Consolidate Docker Compose files | Small | Low | Merge dev + prod into single config |
