#8295

Description (What does it do?)

HubSpot’s Python client changed the BasicApi.create signature to require simple_public_object_input_for_create. This caused user syncs to fail during registration/profile update in MITxOnline with BasicApi.create() missing 1 required positional argument: 'simple_public_object_input_for_create'.

This PR updates ol-django/src/hubspot_api/mitol/hubspot_api/api.py to use the correct v12 create call so single-object contact syncs succeed.

How can this be tested?

1. Install this branch into your local MITxOnline setup (use uv build to generate a new ol-django-hubspot-api pacakge)
2. User registration flow (single create path):

• Register a new user via the app.
• Verify no error in worker logs.
• Confirm the user appears in HubSpot Contacts with expected properties.
• Confirm users_user.hubspot_sync_datetime populated.

3. Profile update flow (single update path):

• Log in as an existing user.
• Edit profile and save
• Verify no error in logs and updated fields are reflected in HubSpot.
