General Vehicle Inspection (HU) System

Adds a realistic General Vehicle Inspection (HU/TÜV) system for all license-plate-equipped vehicles including tractors, trucks, cars, trailers, harvesters, and loading wagons.

How it works:
Every vehicle with an official license plate automatically receives an inspection deadline based on its vehicle class, speed, and permissible total weight (e.g. cars every 24 months, trucks every 12 months, tractors above 40 km/h every 12 months). Expired deadlines are marked as „Due" or „Overdue" – the vehicle remains fully drivable so gameplay is not restricted.

Inspection Station in the Pause Menu:
A green clock icon opens the vehicle inspection registry listing all farms. Select a vehicle and choose an action:

• Enter: Perform inspection – renews the deadline
• C: Deregister/reregister the vehicle
• X: Switch sorting mode
• I: Set a custom inspection interval (3/5/6/9/12/24/60 months)

Initial Setup: The roles „Inspecting Farm" and „Deregistration Authority" can only be assigned by administrators in the game settings.

Multiplayer Ready: All inspection data and settings are stored in the savegame and automatically synchronized between server and clients.

Fully Configurable: Over 60 vehicle categories, classes, and deadlines can be easily adjusted in the huSettings.xml without any coding knowledge.
