feat: configurable vehicle compatibility source (TecDoc / QWEN / Both)

Backend:
- Added GET/PUT /pos/api/config/vehicle-compat-source endpoints
- Added get_compat_source() helper reading from tenant_config
- create_item() now respects config: runs TecDoc and/or QWEN accordingly
- auto_match_item_vehicles() respects config: runs only configured source

Frontend:
- Added 'Compatibilidad de Vehiculos' section in config.html
- Added loadVehicleCompatSource() / saveVehicleCompatSource() in config.js
- Regenerated config.min.js
