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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

+
+## 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 |
+| Extract shared React hooks | Medium | Low | Create libs/ui-hooks |
+
+### Operational Issues
+| Issue | Impact | Mitigation |
+|-------|--------|-----------|
+| **No staging environment** | Prod bugs possible | Deploy to staging branch before prod |
+| **Backup testing manual** | Data loss risk | Automate weekly restore test (CI) |
+| **Monitoring alerts missing** | Incident response delay | Configure AlertManager rules |
+| **No incident runbook** | Team confusion | Create runbook in docs/runbooks/ |
+| **Single PostgreSQL instance** | Single point of failure | Set up read replica + failover |
+
