[Kavita] Apply Multiple Themes / Combine Themes

[Zeoic]

Idea Description

I have made my own personal changes to my local theme and while I quite like all the features I have added via the theme, I can imagine some people would only want certain parts, if any. For example, my one theme adjusts the dark theme to be just a tad darker, and it makes series card titles use two lines instead of one, and it also makes chapters appear in a list view instead of as cards.

I think it would be cool to be able to publish a theme / mini-theme of some sort that is meant to just change one small thing. You could then choose multiple of these themes and apply them all together. In that case, I could make a list view theme, a dual line title theme, a slightly more dark theme, and a theme that only disables color scape, and people could mix and match the features as they see fit.

Extra Ideas for this:

• Maybe add a priority to each added theme which changes the order they are applied in, just in case some themes conflict with eachother a bit
• A theme could also include a compatibility file/variable that could tell users when certain theme combos are not reccomended due to them changing similar things and breaking stuff

I agree this could be very useful for colorscapes. It's been asked a few times about disabling it and currently the only option to do so is to use the theme with it removed or modifying your existing custom theme to remove it.

What you're essentially asking for is akin to the CSS loader decky plugin for Steamdeck where you can turn on or off different isolated styles. https://deckthemes.com/themes?filters=All&order=Most+Downloaded&type=CSS

While I see the benefit it is a major departure to our current system and I'd imagine would require a large overhaul.
