feat: Add endpoint to delete recordings

This commit introduces a new API endpoint for deleting recordings. The
endpoint
handles the removal of the audio file and its associated sidecar files
(transcript,
duration). It also invalidates derived artifacts like oneliner.json,
document.md,
and analysis_input.json. Additionally, it includes checks for path
traversal,
correct file extensions, and case ownership to ensure security and data
integrity.
A new `RecordingDeleted` event is also added to the `CaseEventKind`
enum.
