Recording-schedule watcher. On each tick it asks the recorder to reconcile the time-based
cameras (scheduled / scheduled_event) whose recording state must change because a window just
opened or closed — so a recorder starts when the window opens and stops when it closes, without
waiting for an external API call. Continuous cameras are untouched (their reconcile is event-driven
on config change), and a camera already in the correct state is never restarted mid-window.
Schedule windows are evaluated against the SERVER’s LOCAL timezone (chrono::Local); there is no
per-camera timezone. Spawned (supervised) from main only when the recorder is enabled.
