Claude 95b1a99f2a perf(roms): avoid hydrating full Rom rows for siblings on list endpoint

The paginated ROM list eager-loaded sibling_roms via selectinload, which
hydrated full Rom ORM instances (including heavy JSON metadata columns)
for every sibling even though only an existence/count check was needed
on the frontend. On large collections this dominated request latency.

Split sibling handling by response shape:
- SimpleRomSchema (list): siblings is now list[int]; populated per page
  by a single SELECT against the sibling_roms view projecting only
  (rom_id, sibling_rom_id) — no Rom row hydration.
- DetailedRomSchema (detail): keeps full SiblingRomSchema objects, with
  load_only on (id, name, fs_name_no_tags, fs_name_no_ext) so sibling
  rows stop dragging in JSON metadata.

Frontend usage already only consumes siblings.length on list views; the
detail-page VersionSwitcher continues to receive the richer schema.
