Basically reverting back to an old keymap

- removed most combos and all key overrides
- implemented custom override for haptic and audio config
- went back to older keymap (e.g. backspace and del on most layers)
- reintroduced dedicated mouse button on thumb cluster
- mouse button 2 is now a combo
