Updates to details pages including videos' stream details display (#279)

## Details

This PR updates the detail pages for Movies & TV Shows.

- Increase backdrop image size & brightness (now matches home page)
- Increase max width for titles
- Decrease max width for detail text
- Switch to using a customized display labels for video, audio, &
subtitle streams

Additional change for movie pages:

- Don't dim movie details text
- Move video stream details below play buttons
- Move first row up higher

### Labels

Instead of using the server provided `DisplayTitle`, create display
labels in-app. In general, this shortens the text without losing
significant detail. It is similar to the official app.

Some of the changes:
- Don't show "SDR", only "HDR"
- Simplify audio channel info, eg "Surround 5.1" => "5.1"
- Show chosen subtitle language
- Show chosen subtitle codec
- Show "(+#)" if there are additional audio or subtitle tracks
- Use gray background slightly tinted by the theme color
