Adds a company selector to the contact details form so agents can
associate a contact with an existing company directly from the contact
page.
Closes
- None
Why
Contacts already expose company information through the CRM fields, but
the form only accepted free-text company names. As we split company CRM
work into smaller PRs, this keeps the contact page aligned with the
structured company model while preserving the existing company-name
behavior used by automations.
What changed
- Shows a company dropdown in the contact details form when the
Companies feature is enabled.
- Keeps legacy free-text company names editable when a contact has no
structured `company_id`.
- Allows Enterprise contact create/update APIs to accept account-scoped
`company_id`.
- Syncs `additional_attributes.company_name` when a contact is
associated with a company, including the existing email-domain
auto-association path.
- Serializes `company_id` in the contact model payload so the form can
show the current association.
How to test
1. Enable Companies for an account and open a contact details page.
2. In Edit contact details, use the Company field to select an existing
company.
3. Save the contact and refresh the page.
4. Confirm the selected company remains visible and the contact is
associated with that company.
5. Confirm contacts with only a legacy free-text company name still show
the text input instead of an empty selector.
