ilaandClaude Opus 4.8 2603a10fb1 feat(v1): settings camera connection test and preview
Settings tab gains a camera group (host/port/channel/user/masked password),
a background connection-test worker that probes one frame off the GUI
thread and shows it in a preview, and a save button that writes the
structured source to the untracked config.local.json. 60 tests pass;
Qt shell compiles and needs a Windows smoke.

"""Thin PyQt5 rendering shell for the V1 monitor and settings tabs.
This module only renders ``MonitorViewState`` and binds ``SettingsDraft``; it
never runs Pose, tracking or fall decisions. All event facts arrive from the
``FallPipeline`` worker in ``v1/app.py``. Because acceptance-critical logic lives
in ``v1/view_model.py`` (Qt-free and unit-tested), this file is the only surface
that requires a Windows + PyQt5 + display smoke test.
