feat: keep opened room visible in sidebar collapsed categories

[dougfabris]

Proposed changes (including videos or screenshots)

Collapsing a sidebar category hid every room in it, including the one you were currently viewing — leaving no indication of where you were in the sidebar.

The open room now stays listed under its category while collapsed. useRoomList reads it from useOpenedRoom() and folds it into the existing collapsed-visibility rule:

const isVisibleWhileCollapsed = (room) => room.rid === openedRoom || (showUnreads && isUnreadRoom(room));

The collapsed header badge now counts only the rooms the group actually hides, so the open room isn't counted both in its own row badge and in the header.
