Fixed
- Eliminated UI flicker during switch toggles
- Problem: Switches showed ON → OFF → ON pattern when toggling
- Root cause: Immediate coordinator refresh returned stale state, clearing optimistic update
- Solution: 20-second settling period keeps optimistic state while device processes change
- Stale coordinator updates ignored during settling period
- UI now shows smooth ON/OFF transitions without flickering back to old state
- Switch state synchronization now rock-solid with optimistic updates + settling period + delayed refreshes
