Added Stakater Reloader to automatically restart Stalwart pods when
TLS certificates are renewed by cert-manager. This ensures seamless
certificate rotation without manual intervention.
Changes:
- Deploy Stakater Reloader in infrastructure/networking/
- Add Reloader annotation to Stalwart StatefulSet to watch stalwart-tls secret
- Document certificate renewal process and troubleshooting
The certificate is managed by cert-manager with Let's Encrypt and will
automatically renew 30 days before expiration (renewal date: 2026-08-20).
Reloader detects secret updates and triggers a rolling restart of the
Stalwart StatefulSet to load the new certificate.
