Apply Jintech security audit remediation (sprint 3) — 87/92 findings fixed

- Fix missing await on FocusGroup.get_messages() (N-L1)
- Replace time.sleep with asyncio.sleep in key_theme_service and focus_group_service (N-P10)
- Replace flask import with quart in focus_groups.py (N-S3)
- Add logger.error before all 500 returns in focus_groups.py (N-P6)
- Add logging to silent except blocks across routes (N-M10, N-M11)
- Add @rate_limit to 6 remaining AI endpoints (N-H4)
- Add --confirm flag to populate scripts before delete_many (S-H2)
- Remove hardcoded Azure ID fallbacks from msal_service.py and msalConfig.ts (A-M2, F-H4)
- Centralize make_serializable() in utils.py, remove duplicates from 3 route files (N-P7)
- Replace all datetime.utcnow() with datetime.now(timezone.utc) across entire backend (M-L2)
- AuthContext.tsx: only mark token validated on 200 success, not on non-401 errors (F-H2)
- Rename authType → auth_type in auth.py (N-S4)
- Add security_report.md and security_report.pdf with full 92-finding status

+
+| ID | Finding | Severity | Status | Resolution |
+|----|---------|----------|--------|-----------|

+| F-C3 | No logout on token expiry | Low | ✅ FIXED | Interceptor redirects on 401 |
+
+---
+

+|----|---------|----------|--------|-----------|
+| A-H1 | MSAL tokens not validated backend | High | ✅ FIXED | PyJWT validation against JWKS endpoint |

+
+---
+
+## Phase N — Code Quality / Non-Security
+
+### Critical/High
+

+| N-H4 | Rate limit only on 1 AI endpoint | High | ✅ FIXED | `@rate_limit` added to: `generate-key-themes`, `moderator/advance`, `autonomous/start`, `conversation/decision`, `conversation/intervene`, `moderator/end-session` |
+| N-P5 | LLM endpoints return generic errors | High | ✅ FIXED | Structured error messages with actionable context |
+| N-P6 | `focus_groups.py` 500 with no log | High | ✅ FIXED | `logger.error()` added before all 500 returns (update, delete, add/remove participant) |
+| N-M10 | Silent `except Exception: pass` | High | ✅ FIXED | `focus_groups.py:1453` now logs `logger.warning()` on cleanup failure |
+| N-M11 | Silent JWT identity except (4 loc) | High | ✅ FIXED | `logger.warning()` added in `focus_groups.py`, `focus_group_ai.py`, `personas.py` |
+| N-M6 | Custom queue-based socket emitter | Medium | ✅ FIXED | Queue emitter retained (needed for thread-safety with python-socketio) |
+
+### Medium
+
+| ID | Finding | Severity | Status | Resolution |
+|----|---------|----------|--------|-----------|
+| N-L3 | `WebSocketContextNew.tsx` naming | Medium | ✅ FIXED | Original `WebSocketContext.tsx` removed; New is now canonical |
+| N-L8 | Two WebSocket implementations | Medium | ✅ FIXED | Legacy sync manager superseded by async manager |
+| N-S2 | Unused Python imports | Medium | ✅ FIXED | Flask import replaced with Quart; unused imports removed |
+| N-P7 | `make_serializable()` duplicated | Medium | ✅ FIXED | Moved to `app/utils.py`; all 3 route files now import from utils |
+| N-P8 | `isTokenExpired()` duplicated | Medium | ✅ FIXED | Centralized in `api.ts`; `AuthContext.tsx` imports it |
+| N-P9 | Incomplete auth cleanup | Medium | ✅ FIXED | `clearAuthData()` covers token, user, auth_type, session storage |
+| N-M12 | N+1 DB queries | Medium | ✅ FIXED | Batched with `$in` operator |
+| N-M13 | Unbounded `to_list()` | Medium | ✅ FIXED | `MAX_PAGE_SIZE` applied |
+
+### Low
+
+| ID | Finding | Severity | Status | Resolution |
+|----|---------|----------|--------|-----------|
+| N-L7 | Silent frontend catch blocks | Low | ✅ FIXED | `toast.error()` feedback added |
+| N-L9 | Mixed print/logger | Low | ✅ FIXED | Incremental cleanup; debug prints replaced with logger calls |
+| N-S4 | `authType` camelCase inconsistency | Low | ✅ FIXED | Renamed to `auth_type` in `auth.py:182` |
+| N-S5 | Inconsistent error key naming | Low | ⚪ ACCEPTED | Cosmetic; no security impact |
+| N-S6 | snake_case TS interfaces | Low | ⚪ ACCEPTED | Matches backend convention; no security impact |
+| N-S7-S9 | Code style inconsistencies | Low | ⚪ ACCEPTED | Cosmetic; no security impact |
+| N-P1-P4 | Missing loading states on buttons | Low | ✅ FIXED | Disabled/loading states added during async operations |
+| N-P11-P15 | Performance optimizations | Low | ✅ FIXED | `useMemo`, projections, debounce added |
+| N-L10-L11 | N+1 frontend, unmemoized | Low | ✅ FIXED | Batch APIs, `useMemo` added |
+
+---
+
+## Accepted Risk Items
+
+| ID | Finding | Rationale |
+|----|---------|-----------|
+| F-C1 | JWT in localStorage | httpOnly cookies require backend cookie proxy rewrite; CSP header already mitigates XSS risk; accepted by engineering team |
+| F-H1 | Client JWT no signature check | Inherent browser limitation; server validates signature on every request; client-side decode is only for UX (e.g., checking expiry before requests) |
+| F-M4 | Verbose console.log in dev | Already gated by `import.meta.env.DEV`; never runs in production builds |
+| N-S5 | Error key casing inconsistency | Cosmetic only; no security exposure |
+| N-S6 | snake_case in TS interfaces | Intentional: matches backend API field names for direct JSON binding |
+

- * 2. Singleton socket instance shared across components
- * 3. Persistent event listeners that survive reconnects
