orohiandCursor 415cfea5eb Fix NaiveProxy share links to always include port 443. 
v2rayN treated links without an explicit port as invalid/80 and failed TLS.

"""
NaiveProxy manager — Caddy + klzgrad/forwardproxy (naive fork).
Server side is the naïve Caddy forward_proxy from:
https://github.com/klzgrad/naiveproxy
https://github.com/klzgrad/forwardproxy
Uses the official prebuilt Caddy binary on amd64, or builds via xcaddy on other
arches. Clients authenticate with HTTP basic auth; share links are
naive+https://user:pass@domain URIs (NekoRay / sing-box compatible).
Requires free TCP 80 (ACME) and 443 (HTTPS / HTTP2 proxy).
