Changelog: 1.2.0.0

AdBlue consumption system reworked
- Consumption now scales realistically with engine load and is fully synchronized in multiplayer.

New in-game AdBlue settings
- Choose between Low, Normal, High, or Custom usage levels.
- Custom value can be entered directly and takes effect instantly – synced across all clients.

Improved engine power limitation
- When AdBlue is empty, engine power is automatically limited to 10 %.
- A clear HUD warning is displayed to the player.

New HUD visuals and designs
- Multiple AdBlue display styles added (Classic, Modern, ExtraBar, Detailed etc.).
- Includes blinking warning when the tank is empty, and improved percentage / fill-level display.

Remaining range calculation
- Diesel and AdBlue remaining hours are now calculated and shown in real time, synchronized in multiplayer.

Fixed tank saving behavior
- Removed automatic 10 % refill – tanks now save and load exact fill levels.

Added idle engine load
- Engines now maintain a slight fluctuating load (4–5 %) at idle for more realistic behavior.

General stability and performance improvements
