Room list: display the menu option on the room list item when clicked/opened (#31380)

* fix: display the menu option on the room list item when clicked/opened

Fix #31366
`onBlur` was called when the room is opened, the focus is moved to the
composr. The hover state was removed.
The hover state is diplayed when `ìsFocused=true` so the keyboard
navigation is not impacted

* test: update room list e2e tests

* test: update marked as unread state
