Original Pull Request: https://github.com/netbirdio/netbird/pull/5583

State: closed
Merged: Yes

Describe your changes

With this change it is not possible to pass a directory path for wildcard certificates to the proxy with NB_PROXY_WILDCARD_CERT_DIR or --wildcard-cert-dir.

The proxy will read all the certificates in that folder and cache for the domains matching SNI.

Summary by CodeRabbit

New Features
- New CLI flag to point the server at a directory of wildcard TLS certificate pairs; matching wildcard certificates are loaded and served immediately.
- Wildcard domains served from provided certificates bypass external provisioning when applicable.
- Background monitoring reloads updated wildcard certificates without restarting the server.
Tests
- Expanded coverage for wildcard parsing, matching, loading, serving, and related edge cases.
