Adds configurable event.require_rapid_drop (default off), require_lower_body
(default off) and horizontal_angle_threshold_degrees (default 45). With the
lenient defaults a sustained horizontal pose alone enters SUSPECT and confirms
after the confirm window, which is now the main false-positive guard; missing
knees/ankles no longer reject the pose. Thresholds flow into config_version.
End-to-end smoke confirms a lying pose; 70 tests pass.

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.

A: PoseAdapter.set_confidence_threshold is applied on start, so the
settings model-confidence field actually affects inference.
B: config source.mode ('stream'|'replay') is explicit; app no longer
guesses the source type from the URL prefix.
C: FallStateMachine takes a session_id and from_config generates a
unique one per run, so event ids never collide across restarts
(no screenshot overwrite or duplicate JSONL identity in a day).
51 tests pass.
