Remove 12 unit tests that accessed socket internals via :sys.get_state
and called handle_async directly — these leak implementation details and
error/exit paths can't be reached through the DOM.
Keep the 3 integration delete tests that use pure DOM assertions: visit,
assert_has, click, refute_has, render_async, DB verification.
Cover current delete behavior across LiveView index and show paths, and strengthen existing delete tests with persistence assertions.\n\nValidation: mise run dev:precommit
Waves 1-2: scrobble_live/index, scrobbled_tracks_live/index, release_group_show, release_show. Dropped unwrap/2 bridges and page_title/1 usage. Search form tests use visit with query params. page_title tests use assert_has("title", ...).
Replace phx-click server event with Fluxon.open_dialog for zero-latency
modal opening. The modal DOM is now always present (no :if conditional) so
it can be shown instantly; the server syncs state in the background.
Fix test selectors that now match the always-present modal form by scoping
to forms without phx-target (which the modal form always has).
