Subject: [PATCH] fix(ipam): Add scope fields to "Add Prefix" button

Update the "Add Prefix" button URL in the child prefixes view to pass
`scope_type` and `scope` (replacing the legacy `site` query parameter).
This allows the prefix creation form to inherit the parent prefix scope
and scope type as expected.

Fixes #21262
