Add native support for Pangolin (self-hosted alternative to Cloudflare Tunnel)

[andrea-tr2]

Many Dokploy users rely on Cloudflare Tunnel snippets to publish services without opening ports, yet that path still depends on Cloudflare's SaaS.

Pangolin achieves the same outward-facing tunnel while remaining fully self-hosted. It runs its own WireGuard relay, exposes private resources through a single outbound connection, and includes the access controls that ordinarily require Cloudflare Access: per-path, role and IP rules, one-time share links, native OIDC (Logto, ZITADEL, Authentik, Keycloak) and forwarding for any single-port TCP or UDP service in addition to HTTP/HTTPS.

Integrating Pangolin mainly involves a lightweight Newt container - https://github.com/fosrl/newt (Pangolin's WireGuard tunnel client, functionally similar to cloudflared.)

Would love to see this implemented

would be genuinely awesome! pangolin seems to be the straight up OS default and alternative for Cloudflare and the team is super positively interactive with community, seems like a stable relationship

Maybe we need to add some docs about this, cloudflare tunnels are working fine docs incoming Dokploy/website#95
