feat(web): add emex + vin-api vehicle attribute extraction

Extend the source dispatcher to the remaining decode sources. emex surfaces its
parsedOptions codes (engine_type/gearbox_type/vehicle_type → Motor tipi /
Şanzıman tipi / Araç tipi), led by any readable DB columns (Vites, Kasa).
vin-api surfaces its flat fields (bodyClass, engineModel, transmissionStyle,
plantCountry → Kasa / Motor / Vites / Üretim ülkesi). Both replace the bare
3-field DB fallback these vehicles showed before.
