Custom terminal fonts support (#5414)

Fixes #5132 #5133 
- bundled 7 new monospaced fonts for terminal
- fix: refresh terminal font after changing in the preferences / keep cluster iframe accessible in DOM while not active/focused
- display terminal's custom font preview with font-name in the select-box + live-preload for current `fontSize`, fix lint

* Fixes for <Input/>:
- remove duplicated error messages for sync validators
- don't propagate invalid values on change (uncontrolled components only)
- more informative error message for numeric input with min/max info
