/**
 * Reporter module — pushes aggregated state to the master dashboard.
 *
 * Every 30 seconds, collects firm-level stats + scheduler state and sends them
 * to the configured master_dashboard_url. Silently skips if not configured.
 *
 * Two transports, in that order of preference: the control WebSocket in
 * `master-link.ts` when it is up, and the original POST /api/report when it is
 * not. The socket already exists for commands, so reusing it saves a request
 * per tick — but a master on an older build has no socket to offer, and the
 * POST keeps those working unchanged.
