Clean up filter dialog

Checklist

• I have used the search function for OPEN issues to see if someone else has already submitted the same feature request.
• I have also used the search function for CLOSED issues to see if the feature was already implemented and is just waiting to be released, or if the feature was rejected.
• I will describe the problem with as much detail as possible.
• This request contains only one single feature, not a list of multiple (related) features.

App version

3.12.0

Feature or improvement you want

• Remove confirm button (this is done in the background anyway)
• Move reset button to the top and make it visually different
  • So it does not look like the button on alert dialogs where you would feel like you need both positive and negative button
  • Maybe add an icon
  • Maybe rename to "clear"

Why should this be added?

No need to confirm when the episodes already updated in the background. Also, it is inconsistent to have "confirm" but not "cancel"
