fix: Critical bug fixes for AI chat and children authorization

## AI Chat Fixes
- **CRITICAL**: Fixed AI chat responding only with sleep-related info
  - Root cause: Current user message was never added to context before sending to AI
  - Added user message to context in ai.service.ts before API call
  - Fixed conversation ID handling for new conversations (undefined check)
  - Fixed children query to properly use FamilyMember join instead of incorrect familyId lookup
  - Added FamilyMember entity to AI module imports

- **Context improvements**:
  - New conversations now use empty history array (not the current message)
  - Properly query user's children across all their families via family membership

## Children Authorization Fix
- **CRITICAL SECURITY**: Fixed authorization bug where all users could see all children
  - Root cause: Controllers used `user.sub` but JWT strategy returns `user.userId`
  - Changed all children controller methods to use `user.userId` instead of `user.sub`
  - Added comprehensive logging to track userId and returned children
  - Backend now correctly filters children by family membership

## WebSocket Authentication
- **Enhanced error handling** in families gateway
  - Better error messages for connection failures
  - Added debug logging for token validation
  - More descriptive error emissions to client
  - Added userId fallback (checks both payload.userId and payload.sub)

## User Experience
- **Auto-clear cache on logout**:
  - Logout now clears localStorage and sessionStorage
  - Prevents stale cached data from persisting across sessions
  - Users get fresh data on every login without manual cache clearing

## Testing
- Backend correctly returns only user's own children (verified in logs)
- AI chat now responds to all types of questions, not just sleep-related
- WebSocket authentication provides clearer error feedback
