A few style tweaks needed from the changes in #8030

• Update nested compact disabled nodes from --on-disabled to --disabled. Right now it's very hard to read in dark theme, and is indistinguishable from regular text in light theme

• Add disabled to disabled nodes (or other things, too, if they need it) that are buttons

• Remove cursor pointer on disabled node. Make sure the cursor is still pointer if there is something enabled in the node

• Remove background color on hover/focus for disabled node - this includes when the node is disabled but the toggle button is still enabled

• Update compact nested toggles to be subtle as default (when not expanded) - for regular compact and secondary background. All toggle icons should be subtle by default

• Change all toggle button icon color to --hover on hover/focus

• Update toggle icon color to --clicked on expanded
