Enhance parseCIDR in utils/ipallowlist.go to support single IP addresses
(without CIDR prefix) and ensure IP is in canonical form. This matches
the functionality previously in access.go.
- Add ParseCIDR as public function supporting CIDR and single IP
- Update access.go to use utils.ParseCIDR instead of local implementation
- Remove duplicate parseCIDR function from access.go
- Update tests to use utils.ParseCIDR

Apply modern Go patterns across the codebase:
- Replace `interface{}` with `any` (Go 1.18+)
- Use `for range n` instead of `for i := 0; i < n; i++` (Go 1.22+)
- Replace `sort.Slice` with `slices.Sort` from slices package
- Simplify sync.WaitGroup patterns with errgroup where appropriate
- Add Makefile targets for modernize analyzer

Conflict: sendfile.go (!linux build tag) was incorrectly modified to
include linuxSendfile and getSocketFd functions which already exist
in sendfile_linux.go.
Resolution: Keep HEAD version (simple fallback returning ENOTSUP) as
Linux implementation is properly separated in sendfile_linux.go.
