feat: Option for viewing sr decks and cards in tabs

[KyleKlus]

This pr implements the ability to open the views (deck view and card view) of the sr plugin in a tab/window, rather than in a modal. This ability is turned off by default and can be turned on via a toggle in the ui settings of the sr plugin.
Further more one can also limit the size of the ui within a tab via the already existing flashcard size setting.

This should also satisfy the issues #819, #950 and #1180 partly, but I can also add the open file in new tab button, if that is alright with you, as I've already implemented that on an unpublished branch.

Please dont merge it just yet; I have discovered, that the button alignment breaks, if one tilts the phone into horizontal mode 😅

I've also discovered that not just my new ui breaks in horizontal mode on mobile, but all the other ui too, so I think, that fixing that should be a different pr, as this one is already getting quite big.

I can take care of fixing that later on in a different pr.
