ONVIF focus + iris control (Imaging service)

CrumbVMS now talks to the ONVIF Imaging service, not just the PTZ service. The practical result: focus and iris are operator-driven from the desktop, just like pan-tilt-zoom.

What's new

• POST /cameras/:id/imaging: focus near, focus far, trigger autofocus, iris

open / close

• Desktop PTZ tile UI exposes those as buttons, mappable into the on-video

panel (see related)

• The .06 LPR camera (Uniview) is now ONVIF-configured and verified on the

real fixture

Why

Focus drift is the silent killer of license-plate cameras. Being able to nudge focus from the desktop client without walking out to the camera is the whole ballgame. The Imaging service was always there in ONVIF; we just hadn't plumbed it.

Backend is deployed. Desktop UI is live in the next build.
