Add S3FileStorage adapter (any S3-compatible backend: AWS, MinIO, Garage) alongside the local adapter, selected via STORAGE_BACKEND. Proxied range streaming via get_object+Range; as_local_path downloads to a tempfile for ffmpeg/fpcalc. Rename track.file_path -> storage_uri across domain entity, ORM, repositories, port, and services, with an Alembic migration. Adds mocked S3 unit tests.

"""ORM model for tracks — the central entity.
|
|
|
|
``id`` is the stable, client-facing ``content_id`` (generated app-side by
|
|
``UUIDPrimaryKeyMixin``) — never regenerate it. Dedup is enforced on both
|
|
``(source, source_id)`` (unique) and ``acoustid_fingerprint`` (indexed) so
|
|
imports/downloads stay idempotent (plan §4, §6.1).
