Fix AutoComplete filter crash, dark mode, and live chip updates

- BrowseSourceController: check `sourceFilter is Filter.Group` instead of
  `filter is List<*>` when comparing old vs new filter state; the old check
  matched Filter.AutoComplete (state is List<String>) and tried to cast it
  to Filter.Group, causing ClassCastException on Search button click
- AutoCompleteItem: replace bare MaterialTheme with YokaiTheme so the
  autocomplete/select UI inherits the app's dark/light color scheme via
  createMdc3Theme instead of always rendering light
- AutoCompleteContent: add local `var chips by remember(initialState)`
  so added/removed tags render immediately as chips without needing to
  close and reopen the filter sheet
