The 'Marked watched' / 'Hidden' notices (and resolving a stale notice on
unwatch/unhide) fired synchronously, before the api.setState call resolved.
When the write failed — e.g. the API was unreachable — the optimistic card
override was rolled back in .catch, but the notice had already been emitted
and lingered, falsely claiming a change that never persisted.
Move all three branches into the .then() so the notice is produced only once
the server has actually applied the change; on failure the card reverts and
nothing is announced (the connection-lost status already explains why).
