Universal Air Suspension 1.7

This update focuses on controller cleanup, Bluebuck compatibility, sound improvements, and general reliability fixes across supported vehicles.

Changes:

- Updated controller bindings to the current per-corner air suspension controls.
- Replaced outdated shoot / lift references in controller input files.
- Added the missing controller input file for the us_semi.
- Improved air.lua stability across all supported vehicles.
- Removed old unused shoot controller logic.
- Fixed MD-Series rear left/right control mapping.
- Fixed UTV rear suspension travel limits.
- Cleaned up stale mod info text.
- Added air suspension sound support.
- Changed the air sound so it plays while the button is held and stops when released.
- Trimmed and cleaned the custom air.ogg sound for smoother looping.
- Added a backup of the previous air.ogg.

Bluebuck Fixes

- Fixed a conflict with the vanilla Bluebuck lowrider setup.
- Renamed the mod’s Bluebuck preset so it no longer overrides the vanilla one:
- Low rider -> Air Low Rider
- Fixed a Bluebuck rear air JBEAM formatting issue.
