Alternative Episode Groupings

Concept:

Implement a frontend dropdown menu on a TV show's page that allows users to toggle between different episode sorting and grouping structures (e.g., DVD Order, Digital Release Order, Story Arcs, specific streaming platform orders).

The Problem:

Currently, users are often restricted to a database's default broadcast episode order. However, many shows (especially anime, long-running cartoons, and shows with messy network histories) have alternative viewing orders that users prefer or are actively using based on the media they own (like DVD boxsets) or the streaming service they are using. When a user's chosen viewing source does not match the default broadcast order, tracking progress becomes confusing and inaccurate.
