Users can now pick any subset of drawer items, in any order, to appear
in the bottom bar. If zero items are selected the bottom bar is hidden.
- NavBarItem enum + NavBarCatalog: every drawer destination gets an id,
label, icon, and route resolver so items can be looked up by id.
- UiSettings gains bottomBarItems: List<NavBarItem>; persisted in the
existing UiSharedPreferences DataStore as a comma-separated enum list.
- AppBottomBar reads the list from UiSettingsFlow and renders a zero-
height spacer (preserving nav-bar insets) when the list is empty.
- New Navigate section at the top of the drawer exposes Home, Messages,
Media, Discovery, Notifications as drawer destinations.
- New BottomBarSettingsScreen under All Settings lets users pin/unpin
entries and drag to reorder (same UX as ReactionsSettingsScreen).
