Private keys never leave agent infrastructure. Agents generate ECDSA P-256
key pairs locally, store them with 0600 permissions, and submit only the CSR
(public key) to the control plane. New AwaitingCSR job state pauses
renewal/issuance jobs until the agent submits its CSR. Server-side keygen
retained behind CERTCTL_KEYGEN_MODE=server for demo/development.
Key changes:
- Dual keygen mode via CERTCTL_KEYGEN_MODE (agent default, server for demo)
- AwaitingCSR job state with CommonName/SANs in work response
- Agent ECDSA P-256 keygen, local key storage, CSR-only submission
- CompleteAgentCSRRenewal server-side flow for agent-submitted CSRs
- DeploymentRequest.KeyPEM for agent-provided keys during deployment
- Dockerfile.agent creates /var/lib/certctl/keys with correct ownership

Add SHA-256 API key authentication with constant-time comparison, configurable
token bucket rate limiter, CORS origin allowlist middleware, and React auth
