feat: refresh buttons invalidate cache and show spinner during refresh

- Add revalidateForRefresh(scope, id) server action for home/library/series
- Library/Series wrappers: revalidate cache then router.refresh(), 400ms delay for animation
- Home: revalidate home-data + path before refresh
- RefreshButton uses refreshLibrary from RefreshContext when not passed as prop
- Library/Series pages pass id to wrapper for context and pull-to-refresh
- read-progress: pass 'max' to revalidateTag for Next 16 types
