feat(discover): snooze affordance on Android + web suggestion cards — #2375

Completes the snooze from slice 3 (#2374), so it's now touchable on both
clients (rule #27 — the server side alone was never shippable).

Copy is "Not right now" everywhere, never a dislike (rule #101). The
parked list even says so out loud: "Nothing here counts against your
taste profile."

Both clients flip the card in place to a "Not right now" state with an
Undo, rather than yanking it out of the grid under the cursor. The row
leaves on the next refetch; the persistent way back is a parked-list
section below the deck. That list isn't optional garnish — a snoozed
candidate is by definition absent from the deck, so without it the
DELETE endpoint is unreachable.

Android routes the write through the offline MutationQueue per rule #100,
as ONE toggle kind (SUGGESTION_SNOOZE_TOGGLE) carrying the desired state
rather than two action kinds. That reuses the LIKE_TOGGLE collapse: a
queued snooze the user has since undone is dropped unsent instead of
replaying after the undo and re-hiding an artist they asked to see. The
collapse helper is now a pure top-level function so that rule is unit
tested rather than inferred.

The repository does NOT enqueue on a 4xx — a permanent rejection would
replay to the same failure and would raise a misleading "will sync when
online" hint. The common case is a 404 from un-snoozing a row that
already lapsed, which is the user's intended end state anyway.

Also: an empty deck used to have one meaning (no listening signal yet).
It can now also mean "you parked them all", so the empty copy branches —
telling that user to go listen to something would be wrong advice.
