[IMPROVEMENT] Add a "Mark as Available" and/or "Ignore" button

Feature Request: Add "Mark as Completed/Available" or Ignore Button
Currently, there is no way to mark problematic media as "completed" or "available," causing recurring issues with shows like Trending Daily shows that frequently reappear due to integrations like Trakt. This leads to resource clogging and clutter. Adding a "Mark as Completed/Available" button to the frontend—alongside existing "retry," "reset," and "delete" options—would allow us to manually set media as fulfilled, preventing re-addition?
