fix(pl24): correct Volvo/Polestar VIN decode (model from vinInfoTable) via thin brand service

Volvo decoded as "Volvo {VIN}" with no real model: the generic Ford-shaped
parseP4VehicleResponse reads window.vehicles/<title>/<h1>, but Volvo ships model/year/type in a
<table id="vinInfoTable"> caption/value grid (Model="V60 Cross Country (19-)", Model yili=2021,
Türü="V60 CC II"). 9 vehicles affected (3 dev + 6 prod).

- Add a per-brand vehicle-info hook (P4BrandHooks.parseVehicleInfo) to the shared P4 engine
  (PL24FordLegacyService); brand values win, generic fills gaps. Backward-compatible: no hook → identical.
- New thin PL24VolvoService supplies parseVolvoVinInfo (vinInfoTable parser); orchestrator routes
  LEGACY_VOLVO decode to it. Categories/drill unchanged (shared engine).

Verified live vs 6 prod Volvo VINs: all decode real models (S80/S60/S40/V40/EX40·XC40/V60 CC) +
correct years; drill intact (motor → 7 subgroups). First step of the per-brand split
(shared core + thin brand services).
