Switch all mods to use -moz-pref and make formatting easier to understand.

[CosmoCreeper]

This pull request switches all mods from -moz-bool-pref to -moz-pref and all :root:has(#theme-{name}) to -moz-pref. The idea is to use Mozilla's built-in functionality for identifying preferences and improve performance by getting rid of :root:has().

Additionally, this pull request improves formatting for some mods as some were originally hard to read and understand.

Feel free to provide suggestions or let me know if I missed anything in the pull request.

Although it wasn't exactly this pull request's fault, the "Show the window controls" option in Zen Minimal Exit Menu was broken, so I decided to fix it.

The "Better Tab Indicators" mod had :has(#theme-{name}) selectors inside of the .tabbrowser-tab selectors, which was technically invalid to begin with, but by cleaning up some formatting, replacing them with the -moz-pref media queries, and adjusting the variable name for custom tab borders, it now works perfectly.
