* controller: enable the DualSense HIDAPI driver, light bar and adaptive triggers
Three additions. SDL was opening a DualSense through the generic gamepad path, so SDL_GameControllerHasLED and SDL_GameControllerGetNumTouchpads both reported nothing and no touchpad events ever arrived - enabling the PS5 HIDAPI driver before SDL_InitSubSystem is what makes the light bar and the existing touchpad support reachable. PadSetLightBar validated its arguments and returned OK without touching the pad; it now drives the LED. PadSetTriggerEffect did the same; it now translates the mode and parameters into a DualSense trigger block and sends it.

Scale the SDK 8-bit motor levels to SDL’s 16-bit range and use SDL’s maximum effect duration. Keep lookup and rumble under the controller lock so hot unplug cannot invalidate the SDL pointer.
Add compact keyboard and mouse mapping with analog-stick defaults and integrate a global remapping editor into the Qt launcher.
Based on the host input remapping work from PR #109.
