validateurl.go is VCS-generic but imported gitea.IsBlockedIP, creating an
unexpected generic→Gitea-specific dependency. Extract IsBlockedIP and its
CIDR list to internal/netutil/ipcheck.go (a neutral shared package).
- gitea/ipcheck.go becomes a thin forwarding wrapper (preserves API compat
for callers within the gitea package)
- gitea/ipcheck_test.go replaced with a forwarding smoke test; full coverage
moves to internal/netutil/ipcheck_test.go
- validateurl.go now imports internal/netutil directly
