Egress CI events in the dashboard and over MCP

The events that Egress CI jobs send with send-events: on were only readable from the API. Now:

Dashboard: AI egress › CI groups the last 7 days by repository and run, with each destination's job, path, container, decision, reason, detections and traffic, and a link to the run on GitHub. Blocked requests still shows only what the gateway refused to your AI agents.
MCP: egress_ci_events filters by repo, workflow, job, run and decision, and summarizes per repository and destination. egress_events is unchanged.
API: GET …/egress/events and its stream take ci_repo, ci_workflow, ci_job and ci_run (and their not_ variants) next to attack_type=egress_ci.
