fix: clear commonsUI deprecation warnings and a GC-flaky DM relay-list test

- Move off deprecated Material3 APIs: rememberModalBottomSheetState ->
  rememberBottomSheetState(Hidden, {Hidden, Expanded}),
  OutlinedTextFieldDefaults.contentPadding -> contentPaddingWithoutLabel,
  and the renamed ListItemColors properties in SlimListItemLayout.
- Drop redundant !! in SnoObjectCardRenderTest (assertTrue already
  smart-casts the payload).
- DesktopDmRelayListConsumeTest: DesktopLocalCache holds users and
  addressable notes weakly, so a GC between two consume() calls dropped
  the newer kind 10050 and let the stale one load into a fresh note.
  Pin the User (which strongly holds its dmRelayListNote) for the
  duration of each test, as the app does for a DM recipient.
