Coolify 4.3.12

Original release notes

Fixes

  • Applied authentication rate limits per real client behind reverse proxies and Cloudflare, preventing visitors from sharing one rate-limit bucket (#11515).
  • Reset a server's unreachable counter after a successful connection check, preventing stale failures and false unreachable alerts (#11417, closes #11416).
  • Corrected placeholder alignment in code editor fields (#11514, closes #11420).
  • Queued Cloud registration verification emails with retries, making delivery more reliable.
