feat(library): set status and rating in one step (#56)

Library rows: the status badge is a menu that saves at once.
Game page: status and rating in the top card, saved on click.
Status changes and hiding a game show an Undo toast.
Other game actions moved into a "..." menu; split and unlink ask first.
New sorts: name, last played, time to beat; "last synced" is gone.
Page numbers and 44 px touch targets on phones.
