fix(api,frontend): delete is the true inverse of adopt, no reseed

/creatures/:id/delete now just removes the row, matching how
POST /creatures (adopt) just inserts one — no side effects on anything
else. The auto-reseed was scope creep for a feature that only ever made
sense as a public marketing-site action; now that delete lives in the app
itself as a per-creature control, that safety net isn't needed.

Adds a Delete button next to Feed/Play/Sleep/Revive on every creature
card, same creatureAction() plumbing as the existing actions.
