* fix(backend): return 404 instead of 500 for audio of failed generations

A failed generation stores an empty audio_path. resolve_storage_path("")
resolved to the data directory itself, which exists, so the route's 404
guard passed and FileResponse raised RuntimeError ("File at path .../data
is not a file"), surfacing as a 500.

- resolve_storage_path now returns None for empty paths
- audio routes check is_file() instead of exists() so directories never
  reach FileResponse
- GET /audio/{generation_id} reports "Generation failed; no audio
  available" when the generation status is failed

* fix(backend): reject empty Path objects in resolve_storage_path

Path("") is truthy, so the previous `if not path` guard only caught
None and empty strings. Callers such as database/migrations.py pass
Path objects, so an empty Path could still resolve to the data dir.
Check None separately and reject paths with no parts.

Also add regression tests asserting the version and sample audio
endpoints 404 when a stored path resolves to an existing directory
(guards the is_file() checks against regressing to exists()).

Addresses CodeRabbit review on PR #893.
