Add setting option for default aspect ratio

[CKraft11]

On the player view even on my 21:9 phone the playback defaults to a letterbox cropped view and I have to manually change the aspect ratio for it to fully cover the screen. An option in settings that would allow me to change it to Cover as default instead of having to change the option every time the player is opened would be great. This is already a known issue with the current solution being a hacky workaround. Thanks in advance!

I have a pull request to add this functionality to the html video player

A temporary workaround for this is to add custom CSS .htmlvideoplayer { object-fit: cover !important } but this will affect all devices and force cover mode on all.

Also there's a bug on Windows 11 (recent updates as of writing) when using Cover mode replicated in Jellyfin 10.8.9 where it stretches in fullscreen on a 2560 x 1440. display. I had to add a hack .videoPlayerContainer { top: -1px !important; }
