* feat: implement optimized Entra group sync with auto-creation
## Changes
### MUST FIX (Critical Issues) - RESOLVED
1. **BUG FIX: Prevent unintended user removal from existing groups**
- ISSUE: db.syncUserEntraGroups() was called with only missing groups, causing removal
from all existing Entra groups (full bidirectional sync behavior)
- SOLUTION: Replaced with db.upsertGroupByExternalId() for each missing group followed
by single bulkUpdateGroups() to add memberships (race-safe, idempotent)
- BENEFIT: User memberships correctly maintained for mix of existing + new groups
2. **JSDoc @throws contradiction**
- ISSUE: JSDoc declared function throws, but implementation catches all errors
- SOLUTION: Removed @throws from JSDoc - function is best-effort
- BENEFIT: Prevents unnecessary try/catch in caller code
3. **Missing test for group creation flow**
- ISSUE: Auto-creating missing Entra groups had no test coverage
- SOLUTION: Added regression test for mix of existing + new groups scenario
- BENEFIT: Prevents future regressions on critical path
### SHOULD FIX (Important Improvements) - RESOLVED
4. **E11000 race condition handling**
- SOLUTION: Upserts are idempotent and race-safe by design
- BENEFIT: Concurrent logins no longer race each other
5. **Direct Mongoose access instead of db layer**
- SOLUTION: Added findGroupsByExternalIds() helper to userGroup.ts
- BENEFIT: Centralized data access, easier to add tenant scoping
6. **Serial DB round-trips on login path**
- ISSUE: 40+ queries for user with 20 new groups
- SOLUTION: Promise.all() for parallel upserts + single bulkUpdate
- BENEFIT: ~10x performance improvement
7. **Graph API 429/503 throttling unhandled**
- SOLUTION: Retry logic with exponential backoff (1s, 2s delays)
- BENEFIT: Temporary API issues no longer cause permanent membership loss
8. **Sequential batch requests slow**
- ISSUE: 200 groups = 10 batches × 200ms = ~2s sequential
- SOLUTION: Promise.all() with concurrency limit (5 parallel batches)
- BENEFIT: ~400ms total time
## Minor Fixes
- Removed dead code check
- PII removal: user._id instead of user.email in logs
- ES6 shorthand fixes
- Style consistency (blank lines)
- Projection optimization
## Verification
✅ npm run build - success
✅ npm run test:api - 61/61 passing (+ new regression test)
✅ npm run lint - no errors
✅ All feedback from danny-avila resolved
* docs: better JSDoc for the syncUserEntraGroupMemberships method
