Fixes #21176: Remove checkboxes from IP ranges in mixed-type tables

When IP addresses and IP ranges are displayed together in a prefix's
  IP Addresses tab, only IP addresses should be selectable for bulk
  operations since the bulk delete form doesn't support mixed object types.

  - Override render_pk() in AnnotatedIPAddressTable to conditionally render
    checkboxes only for the table's primary model type (IPAddress)
  - Add warning comment to add_requested_prefixes() about fake Prefix objects
  - Add regression test to verify IPAddress has checkboxes but IPRange does not
