GUI: wire real feature state and config

Replace the dummy preview controls with the actual settings:

- cards bind directly to the feature state and the existing option
  variables; Active/Bind now drive the same gates as the text menu;
- every feature persists active+bind, including movement, melee and spread;
- config path and build info are real; Reload config re-reads the INI;
- Reset defaults is two-click, restores feature settings/binds and keeps
  the GUI layout;
- window position, category and expanded cards persist under [gui] in the
  same config file; layout saves on drag/category/expand/close;
- mouse bind capture handles all five buttons and consumes the click so it
  cannot re-arm immediately;
- Active/Bind tooltips and full scancode names.

The old text tree stays on F1 for one verification pass.
