Finish implementing the episode's pages

[TemporalAgent7]

See https://datacore.app/episodes (and click on each episode to expand it). This needs to be expanded to include more information from the json, formatted to look nicer.

For individual missions, we can correlate with items.json to get loot drops (and drop rates) with links to items.

For missions (not ship battles) we can also include details about the nodes, such as requirements (skill levels, trait locks, etc.). We can use the IAP code as a starting point for drawing the mission nodes with paths and so on.
