Accept HTTP(S), git:// and SCP-style SSH repository URLs whose host is an
IP address, including bracketed IPv6 such as git@[2a01:4f8::1]:org/repo.git.
The clone runs on the user's deployment server, so the IP block did not
protect Coolify, and SSH URLs with IPv4 already passed.
Loopback, link-local and other reserved addresses are still rejected as
internal hosts. Brackets are allowed only around a valid IPv6 host.
Centralize scp-style Git URL parsing so user@host:path (including custom
usernames and embedded ports) is accepted and converted to HTTPS for
public clones, API create, webhooks, validation, and commit/branch links.
