feat(canonical-lexicon): Ford + BMW fix'leri

BMW (~%81): elektronik terimleri → elektrik (audio/navigasyon/elektronik/
iletisim/multimedya/cruise), "ışık"→aydınlatma; servis/doküman sayfaları →
junk (teknik doküman/servis ve onarım/value parts). Ford (~%74): trans
varyantları speed/spd→sanziman, motor varyantları diesel/dohc→motor, gövde→
panjur. 23/23 test.
