Rationale: Oracle cannot reach NAS (Tailscale userspace mode on NAS, no TUN),
the old pull+webhook design requires Edge to download video from NAS and
callback to NAS - both blocked. New design is one-way NAS -> Oracle:
- FAM-Edge: new POST /api/edge/video/push endpoint accepts multipart video
upload, reuses existing OpenCV scene-change keyframe selection, analyzes
synchronously and returns the result payload directly in the HTTP response
(no webhook callback). Old /api/edge/video/analyze kept for compatibility.
- FAM-Edge: VideoPreprocessor.save_upload() saves the uploaded file
- FAM-Edge: AIOrchestrator.process_push_task() runs the full pipeline
(health check -> extract -> select -> compress -> VLM -> fusion) and
returns callback-style payload dict
- FAM-Core: Dispatcher rewritten to push mode - reads local video file,
uploads with task metadata (camera_name, event_start_time from file mtime,
known_members_context), applies the result to DB via shared
event_receiver.apply_success_event()
- FAM-Core: event_receiver success logic extracted into reusable
apply_success_event() (used by both webhook route and dispatcher)
- config: edge_url -> /api/edge/video/push, push_timeout 1800s, gunicorn
Edge timeout raised to 1800s for long synchronous analysis
