Small follow-up release for the achievement toast and admin testing flow.
- Unlock toasts now roll from the achievement title into the badge description instead of a blank second stage.
- Achievement popups show during playback by default again; existing profiles are migrated away from the old accidental mute-during-playback default.
- Admin testing is easier with a server-user picker on the achievement admin/config pages.
- Fallback script injection now cache-busts by plugin version on read-only Jellyfin web roots.
