[Feature]: mark revoked certificates as revoked in the dahsboard

[LuCol96]

Is your feature request related to a problem?

After revoking a certificate via the Acmebot dashboard (ACME revocation is sent
to the CA successfully), the certificate remains visible in the dashboard with
no indication that it has been revoked or disabled.

Current behavior:

• Certificate is revoked at the CA (e.g. ZeroSSL shows it as revoked)
• Key Vault certificate remains enabled=true unless manually changed
• Dashboard shows the certificate as active with no revoked/disabled indicator

Describe the solution you'd like

Desired behavior:

• If a certificate's enabled flag in Azure Key Vault is set to false,
  the dashboard should reflect this visually (e.g. badge "Disabled" or greyed out).
• Optionally: After a successful revoke via Acmebot, automatically set
  enabled=false on the Key Vault certificate.

Why this matters:
Without this feedback, there is no way to distinguish active certificates from
revoked/disabled ones in the dashboard. This creates confusion in environments
where certificates are revoked but not immediately deleted.
