upkeep/scripts: Reorganize JS

[Sidsector9]

Description of the Change

Currently the asset files don't have a structure that makes it easy to search or develop functionality.
This PR moves the assets under src/js/features directory.

Previously, we have Classification and TTS features inside the same file, and it was done because the settings for both had to be rendered inside the Document Panel.

This PR exposes the <ClassifaiEditorSettingPanel /> component on the global window object which can be used b y both internal and 3rd-party developers to extend the Panel area to add more components.

How to test the Change

Thanks for working on this @Sidsector9, This is great. The code looks good. However, I noticed 2 minor CSS things and added notes for the same could you please help look into it? Once it is resolved we would be good to merge this.

Thank you.

It seems the language processing CSS file contains some CSS of the time generation model. Removing this minor break style of the title generation model. Need to move those CSS to classifai-plugin-classic-title-generation.css.

It seems the language processing CSS file contains some CSS of the excerpt generation model. Removing this minor break spacing above the button.
