These three brands rendered parts with NO schema illustration (and no hotspots):
schema_pics=0 vs 56/29/19 parts on dev. Root cause: extractPsaImageTicketUrl only
read imageViewerParamsUrl from the id="jsinitparams" data-params attribute (where
Ford/PSA/Opel/Volvo put it). Hyundai/Kia/Nissan's jsinitparams carries only a
localization dict ({"commonTxt":{"ok":"TAMAM"}}); their imageViewerParamsUrl lives
in a separate <script> JSON blob → extractor returned null → image pipeline skipped.
Fix: when the jsinitparams-attribute parse yields no URL, fall back to a whole-HTML
scan for "imageViewerParamsUrl":"…" (decoding &). Brand-agnostic and additive;
Ford/PSA/Opel/Volvo unchanged (attribute path still wins). Proven live via the de
client: Hyundai 600x820/3 hotspots, Kia 600x820/11, Nissan 1024x560/13 — all download OK.
Also: drop a pre-existing noParameterAssign in fetchP4Page (derive `account` const
from `accountParam` instead of reassigning the param). +3 extractor unit tests.
