pass giteaRepo to agent runner; add runner secret auth on PATCH

- Sessions route now reads giteaRepo from project.data and forwards it
  to /agent/execute so the runner can clone/update the correct repo
- PATCH route now validates x-agent-runner-secret header to prevent
  unauthorized session output injection
