Update vehicle cards to show complete motor specs

Vehicle cards now display 6 motor data fields:
1. Fuel type (Gasolina/Diésel/Híbrido/Eléctrico)
2. Power (HP)
3. Torque (Nm) - NEW
4. Displacement (formatted as liters, e.g., 3.0L)
5. Cylinders
6. Engine config (V6, I4, etc. - derived from name)

Changes:
- dashboard.js: Added helper functions for formatting
  - getEngineConfig(): Extracts V6, I4, H4, etc. from engine name
  - formatDisplacement(): Converts cc to liters
  - formatFuelType(): Spanish translations
- server.py: Added torque_nm to vehicles API response
