Add the schema backing per-monitor object detection and the AI dataset/
model/class management UI:
- Monitors gains AnalysisImageOpacity and ObjectDetection,
ObjectDetectionModel, ObjectDetectionObjectThreshold,
ObjectDetectionNMSThreshold columns.
- New tables AI_Datasets, AI_Models, AI_Object_Classes,
AI_Detection_Settings and AI_Detections.
- Seed the COCO 2017 dataset (80 classes) and default per-class
detection settings via db/coco_dataset.sql.
Existing installs get zm_update-1.39.17.sql, which is idempotent and
adds the columns with their final VARCHAR(16) ObjectDetection shape
directly (no enum-churn intermediates). Fresh installs create the same
objects from zm_create.sql.in sourcing AI_Models.sql and
coco_dataset.sql. Both paths were verified to produce identical schema.
