fix(w7): always show the Recent Rooms card, with an empty state

The card was hidden entirely when there was no history, so on a fresh
build it appeared to be missing. Always render it (with a "No recent
rooms yet" hint when empty), mirroring the Friends card, so the feature
is discoverable before the first join. Drops the has_recents gating in
the home layout.
