fix(lists): optimistic increment and snapshot to remove refresh flash

Click + on a Due item now bumps progress locally and drops the row
if the bump catches the user up, with no upfront refresh. The mutation
fires in the background and triggers a single revalidate on response.
Also snapshot the resolved media to previousAnimeList on every render,
so refreshes from any path (countdown, interval, manual, post-increment)
show the prior list during pending instead of a placeholder.
