Non-host room members were getting 403 errors when trying to select games.
Added proper UI restrictions and messaging to clarify only the host can
select games.
**Changes**:
1. **Host Detection**: Check if current user is room creator
- Find `currentMember` in `roomData.members`
- Check `isCreator` flag
2. **Visual Restrictions**:
- Game buttons disabled for non-hosts (opacity: 0.4, cursor: not-allowed)
- No hover effects when disabled
- Clear visual feedback
3. **Messaging**:
- **Host**: "👑 You're the room host. Select a game to start playing."
- **Non-host**: "⏳ Waiting for [Host Name] to select a game..."
- **Error**: "⚠️ Only the room host can select a game. Ask [Host] to choose."
4. **Error Handling**:
- Client-side check before API call
- Server error caught and displayed with host name
- Auto-dismiss after 5 seconds
**UX Flow**:
- Non-hosts see disabled games with clear "waiting for host" message
- If they somehow click, they get clear error message
- Host sees active games with confirmation they can select
Prevents confusing 403 errors and clarifies room permissions.
