Raise alerts: failed or paused prints, and AI detections

Nothing subscribed to channel:print_alerts and nothing watched a printer fail, so an operator away from the screen found out when they came back to a ruined plate. Alerts are now rows in printer_alerts, listed at GET /alerts (open=true for what still needs a person) and cleared with POST /alerts/:id/acknowledge, which is operator-only and keeps the first acknowledger on the record. Two sources. Telemetry: a change into error is a failed print if the printer was printing or paused, otherwise a printer error; a print the printer paused itself (how an AMS fault looks) is announced too. Transitions, not levels - a printer sitting in error is one alert, not one per frame - and a connection's first sight of a printer raises nothing, so a gateway that reconnects does not re-announce known faults. AI: the worker's Valkey publications are stored when confidence is at least ALERT_MIN_CONFIDENCE (default 0.6); the worker deliberately does not threshold, so the policy lives here. A bad message costs one message, not the listener. e2e-authz.sh gains the scoping/ack cases; new e2e-alerts.sh drives a stand-in gateway over the real /ws/edge/v1 and the real Valkey channel (checked to fail when the derivation is broken).
