Georges-Antoine Assi ce8c1ed049 perf(scan): fetch rom files on demand for metadata matching ...

The scan loaders no longer eager-load `Rom.files` (#3425 + follow-ups), so
the hash-based metadata lookups can't rely on `rom.files` being populated —
`hasheous`/`ss` `lookup_rom` read `RomFile.is_top_level`, which dereferences
`RomFile.rom.full_path` and would raise `DetachedInstanceError` once the
session closed.

Add `DBRomsHandler.rom_files_for_rom_id`, which loads a ROM's files on demand
with the `RomFile.rom` backref eager-loaded (`load_only(fs_path, fs_name)`).
The scan path uses it as a fallback only when the filesystem walk yielded no
files (e.g. an unchanged rescan), behind a per-ROM `functools.cache` helper so
the playmatch/hasheous/ss lookups share a single DB fetch.
