List raw assets available for a recording

Works with: Personal token

Reports the status of every raw asset of a recording, keyed by type (`screen`, `camera`, `microphone_audio`, `system_audio`, `aligned_transcription`, `mouse_events`, `keyboard_events`), so a client does not have to probe each one. An entry is `ready` (the file exists, with its size and the path to fetch it), `processing` (still being produced; poll), `requires_processing` (screen and camera are merged on first request, which returns 202 until done) or `unavailable` (with the reason it will never exist). If the recording is still processing or its processing failed, returns the public processing status instead of a manifest; the mouse and keyboard captures are written at capture time and can still be fetched directly on a failed recording. Raw assets are always the original recording's captures: an edit's `public_id` resolves to the recording it was cut from, the edit's cuts are not applied, and the response's `public_id` is the original's. For the edited video use `/download`. Requires a personal token, edit access to the recording, the `recording:download` workspace capability (or ownership of the recording), and the raw-asset download plan feature on the recording's workspace.
