ML-182.5: migrate blocked LiveView tests

Replace direct LiveView PID and isolated component test patterns with PhoenixTest-backed page flows while keeping narrow unwrap bridges where PhoenixTest cannot express the component interaction.

+Approved implementation plan:
+
+1. Convert index PubSub tests in `collection_live/index_test.exs` and `wishlist_live/index_test.exs` from raw `LiveViewTest.live/2` plus `send(view.pid, :records_index_changed)` to PhoenixTest `visit/2` sessions plus the real `MusicLibrary.Records.broadcast_index_changed/0`. Assert the newly-created record appears on `:index` pages and remains absent while the import modal action ignores the message.
+2. Convert remaining raw `live/2` import-flow tests in collection/wishlist to PhoenixTest pipelines (`visit`, `fill_in`, `click_link`, `click_button`, `assert_path`) and use DB assertions for the dynamically-created redirected record.
+3. For cart format-change and Release component nested-form interactions, use PhoenixTest as the outer session and keep the smallest `unwrap/2` bridge only for the label-less/nested LiveComponent form change that PhoenixTest cannot express directly.
+4. Replace `release_test.exs` `live_isolated/3` coverage with parent LiveView coverage: `CollectionLive.Show` for `show_print?: true` and `ScrobbleLive.ReleaseShow` for `show_print?: false`.
+5. Convert `record_actions_test.exs` to PhoenixTest `visit/2` where practical; for the chat-count test, trigger the real Chat component `send_message` flow instead of directly sending `{Chat, :chats_changed}` to the LiveView PID.
+6. Run focused tests for the four task files, then `mix format` on changed files. Update the task notes/final summary and check any acceptance-style completion evidence even though this task has no explicit acceptance criteria.

+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+Implemented the approved PhoenixTest migration plan for the four scoped files. Direct LiveView PID messaging was replaced with real PubSub broadcasts or UI/component flows; `live_isolated/3` Release coverage was replaced with routed parent LiveViews; raw `live/2` import flows were converted to PhoenixTest session pipelines. Kept small `unwrap/2` bridges only for interactions PhoenixTest cannot express directly: cart native-select `phx-change`, Release component nested form changes, record action event dispatches, and Chat component form submit.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Converted the ML-182.5 test files away from raw LiveView PID/isolation patterns while preserving the existing behavioral coverage.
+
+Changed:
+
+- `collection_live/index_test.exs`: PubSub tests now use `Records.broadcast_index_changed/0`; import flows use PhoenixTest session pipelines; cart format changes keep a narrow `unwrap/2` helper for the component form change.
+- `wishlist_live/index_test.exs`: PubSub and single-item import tests now use PhoenixTest-style navigation and async path assertions.
+- `record_actions_test.exs`: page-level tests now mount with `visit/2`; the chat-count test triggers the real Chat component submit flow instead of `send(view.pid, ...)`.
+- `components/release_test.exs`: removed the isolated host LiveView and replaced `show_print?` coverage with `CollectionLive.Show` and `ScrobbleLive.ReleaseShow` parent pages.
+
+Validation:
+
+- `mix format test/music_library_web/live/collection_live/index_test.exs test/music_library_web/live/wishlist_live/index_test.exs test/music_library_web/live_helpers/record_actions_test.exs test/music_library_web/components/release_test.exs`
+- `mix test test/music_library_web/live/collection_live/index_test.exs test/music_library_web/live/wishlist_live/index_test.exs test/music_library_web/live_helpers/record_actions_test.exs test/music_library_web/components/release_test.exs --max-failures 5` -> 52 passed
+- Blocker scan for `live_isolated`, `send(view.pid)`, raw `LiveViewTest.live`, `assert_redirect`, and `LVT` returned no matches in the scoped files.
+- `git diff --check` passed.
