BREAKING CHANGES

db: Database schemas now accept any string for game names
Added DELETE /api/arcade/rooms/:roomId/invite endpoint for declining invitations

Authorization Error Handling:

ModerationPanel: Parse and display API error messages (kick, ban, unban, invite, data loading)
PendingInvitations: Parse and display API error messages (decline, fetch)
All moderation actions now show specific auth errors like "Only the host can kick users"

New Endpoint:

DELETE /api/arcade/rooms/:roomId/invite: Allow users to decline their pending invitations
- Validates invitation exists and is pending
- Only invited user can decline their own invitation
- Returns proper error messages for auth failures

Bug Fix:

Fixed invitations/pending/route.ts ban check query (removed reference to non-existent unbannedAt field)
Ban records are deleted when unbanned, so any existing ban is active
