Easy win: Podcast filter option language should be consistent everywhere

[beckibloom]

Problem
I often filter my podcasts by "Not finished". Inside the "Filter and sort" menu, the option is called "Not finished". However, when viewing the actual podcast page, the information near the filter icon says "Unplayed". On each episode, it says "Finished". So it seems like it is using "Unplayed" and "Not finished" to mean the same thing. I have two problems with this:

1. Mental load: The main problem is when I tap on the filter area to change the filter, I see "Unplayed" where I'm clicking so I'm instinctually looking for language like "Played" or "Unplayed", but that's not what appears in the actual menu, so my brain has to gets thrown for a loop every time I have to re-remember that "Not finished" is actually the same thing.
2. Different meanings: "Unplayed" and "Not finished" have slightly different meanings: "unplayed" implies that it has not been played at all, and "not finished" may mean that it has been partially played OR not played at all.

Easy solution

Since the filter actually shows episodes that have been partially played, it makes the most sense for the language to be "Not finished" everywhere, as it would reduce the mental load from the first problem AND better align with the actual filtered results.
