fix: improve kicked modal message for retired room ejections

**Socket handler update:**
- Capture reason field from kicked-from-room socket event

**Modal UI improvements:**
- Detect when reason contains "retired"
- Show 🏁 emoji instead of ⚠️ for retired rooms
- Title changes from "Kicked from Room" to "Room Retired"
- Message explains room owner retired the room and access is closed
- Clarify only room owner can access retired rooms
