Subject: [PATCH] Fix LPR vehicle message for multiple models (#24119)

* use the camera's model for the lpr vehicle check

`FrigateConfig.model` became `models[]` in the detector refactor, so this didn't compile on 0.19. Each camera has its own detector/model pair now, so the check resolves the camera's scene with `getModelForCamera` instead of looking at every model.

* use camera config model

* fix export test
