Combo highlight config, tooltips, nameplates, hotbars fixes

- Combo highlight: configurable color, glow, line style (solid/dashed/dotted), thickness
- Tooltips: font selection, scaling slider, improved wrap/cramping handling
- Nameplates: custom quest icons with config, position smoothing fix for jitter
- Hotbars: hide keybinds on empty slots, combo highlight within icon bounds
- HudHelper: restore default nameplates on plugin disable
