Function apply_registration

atomic-cli/src/commands/identity/register.rs:373–428

Record a completed registration in the global config. Two shapes, matching the pre-existing behavior: - `profile_name = Some(_)` (an `--identity` registration): insert a named `[servers.{name}]` profile carrying the URL, org, and identity binding. It becomes the active profile (`default_server`) only when nothing is active yet AND the legacy `[server]` block is unconfigured. - `profile_name = No
