* continue to use paddleocr v3 text detection model for large
v5 was not finding text on multi-line plates at all in testing
* implement clustering of plate variants per event
should reduce OCR inconsistencies and improve plate recognition stability by using string similarity to cluster similar variants (10 per event id) and choosing the highest confidence representative as the final plate
* pass camera
* prune number of variants based on detect fps
* implement replacement rules for cleaning up and normalizing plates
* docs
* docs
* fix onvif reinitialization
* api docs: clarify usage of clip.mp4 endpoint
* Always show train tab
* Add description to API
* catch lpr model inference exceptions
* always apply motion mask when using yolov9 plate detection
* lpr faq
* fix incorrect focus when reopening search detail dialog on video tab
* only use keyboard listener in face library when train tab is active
