PersonAnalysis now carries the policy Evidence; view_model builds a Qt-free
per-person diagnostic line (acc/horiz/ang/rapid/cand/state, or the reject
reason) and VideoView overlays it in a corner. Read-only, no decision change;
locates where a real fall stops. 67 tests pass.

Qt-free view_model builds monitor view state and isolates the settings
draft from the running config snapshot; gui.py/app.py are a thin PyQt5
shell that only renders already-decided FrameAnalysis. 39 tests pass.
