Replaces duplicated inline vi.mock('$lib/api/likes', ...) blocks with
the emptyLikesMock() helper, and (where previously left in working
tree by a parallel quarantine sweep) rolls in the matching
emptyQuarantineMock() switchovers in the same files.
Together with commit dd67f28 — which already swept the four search/*
test files for likes — this completes the 18 likes-mock conversions
called out in #375.
LikeButton.test.ts kept inline — it uses a state-driven mock to
assert the toggle behavior.
SKIPPED:
- liked.test.ts: re-exports createLikedTracksInfiniteQuery and the
album/artist variants that emptyLikesMock() doesn't provide.
- playlist.test.ts: hand-rolled { subscribe, data } stub instead of
readable(...) — different store contract.
