fix(ndbc): restore station deployment hierarchy severed by prior PUT

The fix_platform_links.py PUT to /deployments/{id} was treated by csapi-go-v2
as a full replacement, silently dropping the ogc-rel:parentDeployment link and
promoting all 5 station deployments to top-level.

reparent_station_deployments.py:
- Deletes the 5 orphaned top-level station deployments
- Re-POSTs each under /deployments/{group_id}/subdeployments with the
  corrected platform@link.href (includes /systems/ segment)
- Executed live 2026-05-10; hierarchy restored under NDBC Buoy Stations

bootstrap_ndbc.py: _deploy_station() now accepts base_url so future bootstrap
runs produce the correct href from the start. PUT-based updates to change
deployment properties must be issued via /deployments/{parent}/subdeployments
or the parent link must be explicitly re-included.

+"""Re-parent the 5 NDBC station deployments back under the Buoy Stations group.
+
+The previous PUT to update platform@link.href used the root /deployments/{id}
+endpoint which the server treated as a full replacement, severing the
+ogc-rel:parentDeployment link and promoting each deployment to top-level.
+
+Fix: delete each orphaned deployment, then re-POST under the correct parent via
+/deployments/{group_id}/subdeployments with the correct platform@link.href.
