feat(app): undo every step of a study session, deletions held until it ends

The header's Undo takes back ratings, burials and deletions, last first,
across the session's rounds and from the end of a round, and shows the
card again. A card deleted during a session is held (DelayedDeletions.hold)
until the session ends, then goes after the usual time to undo, so the
message offering Undo still works; if the app is killed first, the card
stays. Undo on a burial's or deletion's message takes back that step alone.
