feat: use EntitySelector for light entity selection with search support (#1335)

Replace cv.multi_select with HA's EntitySelector for the lights field
in the options flow. This provides:

- Built-in search/typing to find entities faster
- Better UX with HA's native entity picker
- Improved handling of renamed entities

Closes #1208
