Subject: [PATCH] fix(radio-tile): allow standalone `RadioTile` usage (#2136)

Although `RadioTile` is meant to be used inside a `TileGroup`, it feels
unpolished for standalone usage to crash due to a missing parent context.

This fixes `RadioTile` to fail open by providing a no-op `add: () => {}`
when `TileGroup` context is not found.
