test: add tests for trash notes filtering and UI

- Added filterEntries tests: trash excluded from all/section/topic/archived,
  trash filter returns only trashed entries
- Added NoteList render tests: trash header, TRASHED badge, 30-day warning
  banner, empty trash state
- Updated all test files with trashed/trashedAt fields on VaultEntry mocks
- Updated useNoteActions to include trashed/trashedAt on new entries
