Fuel Consumption HUD V1.1

Displays fuel usage in l/h for combustion vehicles and instantaneous power in kW for electric vehicles. Anchored to the bottom-right HUD corner and scales with the UI. Hidden for other vehicle types. – Electric behaviour improvements: * Shows instantaneous power (kW) while the electric motor is ON even when stationary. * Shows 0.0 when the motor is OFF to avoid confusing residual values. * Improved consumer-based fallback estimation for electric power usage. – Faster, more responsive internal sampling while keeping the on-screen display stable. – HUD appears instantly when you enter a vehicle (placeholder shown immediately; accurate values follow shortly). – Smoother, more plausible readings with reduced spikes and erratic values. – UI scaling fixes: HUD position and size stay consistent across UI scales (including small scales such as 50%). – Respects in-game HUD visibility (won’t show when the in‑game UI is hidden). – Stability fixes: added runtime guards to avoid rare “attempt to call a nil value” crashes.
