ui: improve controls UX with racing defaults, global search, and mapper developer bindings

Refactor and extend the Controls menu to improve usability for both players and mappers.

- Updated default driving bindings to follow common racing conventions
  (WASD and arrow-key friendly steering/accel/brake layout), and removed
  conflicting defaults.
- Clarified controls-menu behavior and flow around rebinding and defaults.
- Redesigned the search concept to work globally across categories instead of
  being limited to the currently selected section.
- Added a new optional DEVELOPER category for Bezier editing commands, intended
  for mapping workflows.
- Added 14 Bezier-related actions as bindable commands (all unbound by default):
  - moveBPoint +/-X, +/-Y, +/-Z
  - moveBHandle +/-X, +/-Y, +/-Z
  - prevBPoint / nextBPoint
- Made the DEVELOPER category hideable via UI toggle/cvar so normal players are
  not exposed to mapper-only controls unless explicitly enabled.

This keeps the standard player experience clean while enabling advanced mapping
input workflows directly from the controls UI.
