Clean up dependencies

[FourIsTheNumber]

My understanding of dependency annotations is a bit shaky, but I think this is correct.

• Crafttweaker is only used in an optional file behind an isModLoaded check and the api would be interacted with through Zenscript, so I lowered it to compileOnly.
• Nothing in the mod is really exposed as part of a public API except for the QED registry, so I lowered all api dependencies to implementation.
• The TODO for ModularUI1 is very outdated, I think. I can't find any reference to the mentioned class and I tested a bunch of GUIs with the dependency removed, so I think this can be removed now.
• Postea needs to be compileOnly.
• I also temporarily removed Angelica as a testing dependency because GTNHLib causes constant crashes from its model system due to lack of thread safety.
