Feature: Messaging  
Bug: Message styling UX problems

## FIX PLAN - 3 BUGS TO RESOLVE

### FIX #1: JavaScript TypeError (Line 253) - PRIORITY 1
**Problem**: event.target.closest() called but no event parameter
**Current**: async function openConversation(userId, userName)
**Solution**: Add event parameter OR remove event.target usage
**Approach**: Remove the problematic line, use different method to find active item

### FIX #2: Variable Logic Design (Line 247) - PRIORITY 2  
**Problem**: currentUserId stores partner ID, should store YOUR user ID
**Current**: currentUserId = userId; (partner ID)
**Solution**: Store your own user ID, use separate variable for partner
**Approach**: Add currentUserActualId variable, get from backend/session

### FIX #3: Message Styling Logic (Line 177) - PRIORITY 3
**Problem**: Compares sender vs partner, should compare sender vs yourself
**Current**: msg.sender_id === currentUserId ? 'sent' : 'received'
**Solution**: msg.sender_id === currentUserActualId ? 'sent' : 'received'
**Depends**: Fix #2 must be completed first

## IMPLEMENTATION ORDER
1. Fix TypeError by removing event.target usage
2. Get actual user ID and store in new variable  
3. Update message styling logic to use correct comparison
4. Test each fix incrementally

## EXPECTED OUTCOME
- No JavaScript errors
- Your messages: Right-aligned, blue background
- Partner messages: Left-aligned, gray background
- Correct class assignments: sent vs received

## ROLLBACK PLAN
Git branch allows easy rollback to working state if issues arise.
