Remove the per-user oneliner watermark, which was previously used to generate ETags for the `/api/oneliners` endpoint. The watermark was intended to track the last successful oneliner write for each user. The ETag generation has been refactored to use a deterministic FNV-1a hash. This hash is computed over a sorted list of tuples containing `(case_id, last_recording_at_ns, oneliner_mtime_ns)` for all visible cases. This approach ensures that the ETag changes whenever any listen-relevant file system modification occurs, such as a new recording, oneliner regeneration, soft-delete, undo, or upload-auto-reopen. This new method is more robust and avoids the complexity of managing per-user state. The `OnelinerWatermark` type alias and its associated logic have been removed from `AppState` and the relevant modules (`transcribe::worker`, `transcribe::recovery`, `routes::oneliners`, `main`). New integration tests have been added to verify that various delete operations (single delete, undo delete, bulk delete) correctly trigger an ETag update, ensuring cache invalidation.
