sabsariandClaude Opus 4.8 cc164bad6b Add EJBCA UpstreamAuthority plugin support to spire-server chart (#873)
Add support for the EJBCA UpstreamAuthority plugin, allowing the SPIRE
server to use an EJBCA instance as its upstream CA over mTLS.

- Add upstreamAuthority.ejbca values (hostname, caName, endEntityProfileName,
  certificateProfileName, optional endEntityName and accountBindingId).
- Render the ejbca UpstreamAuthority block in the server config and count it
  toward the single-upstream-authority guard.
- Mount the mTLS client credentials (and optional CA cert) from a secret,
  either chart-created (secret.create) or externally provided.
- Gate ca_cert_path on secret.data.caCert, mirroring the disk plugin's bundle
  handling for deterministic rendering.
- Regenerate the chart README and add a unit render test.
