feat(cache): instant list revalidation from command palette and debug menu

Replaces one-shot boolean revalidateAnime with a counter store so
multiple components can subscribe without race conditions. Adds
revalidateManga store and reactive refresh blocks to DueAnimeList
and MangaListTemplate. Extracts shared invalidateListCaches function
used by both the command palette action and the debug settings button.
Renames palette item to "Refresh" and debug button to "Invalidate".
