feat: add comprehensive logging for member addition tracking

Added detailed console logging to track member addition process:

Client-side (AddMembersModal):
- 🚀 Starting member update
- Selected members count and names
- Team leader info
- 📤 Sending to database with count
- ✅ Success confirmation with count
- ❌ Failure logging with error details

Server-side (updateProjectMembers):
- 🔧 Server-side update starting
- Project ID and member count
- Existing members count in DB
- Members being deleted
- Members being inserted (IDs and roles)
- ✅ Success with final count
- ❌ Error details

Example output when adding 3 members:
```
🚀 [AddMembersModal] Starting member update
   Selected members count: 3
   Selected member names: ['John Doe', 'Jane Smith', 'Bob Johnson']
   Team leader: Alice Manager
📤 [AddMembersModal] Sending to database
   Total members (including team leader): 4
   Project ID: abc-123
🔧 [updateProjectMembers] Server-side update starting
   Project ID: abc-123
   Members to add: 4
   Existing members in DB: 1
   Old members deleted, preparing inserts...
   Inserting members: 4
   Member IDs: [id1, id2, id3, id4]
   Roles: ['team_leader', 'member', 'member', 'member']
✅ [updateProjectMembers] Successfully inserted 4 members
✅ [AddMembersModal] Update successful!
   Members added: 3
```

This helps verify bulk addition is working correctly.
