refactor: remove connectivity-off illustration from CastBottomSheet

Removes the `WifiOffIllustration` component and the conditional logic that displayed it when connectivity was disabled. The `CastBottomSheet` now proceeds directly to the scanning state or device list regardless of the `allConnectivityOff` flag.

- Deleted `WifiOffIllustration` private composable.
- Removed `allConnectivityOff` check within the lazy list.
- Cleaned up unused imports.
