/**
 * Built-in CRM integration: upserts a HubSpot contact on every submission.
 * Same architecture as Mailchimp_Integration (a single site-wide Private
 * App token — Settings::get('hubspot_access_token') — per-form enable
 * toggle, WP-Cron retry on failure) and the same Contact_Field_Mapper
 * lookup for email/first-last name.
 *
 * Properties are deliberately limited to HubSpot's own built-in contact
 * properties (email, firstname, lastname) rather than an arbitrary custom-
 * property mapping UI — HubSpot rejects a write to any property that
 * doesn't already exist in the target portal, so mapping to anything
 * beyond these three guaranteed-to-exist ones would need a live property
 * list + UI this first version doesn't build, the same scope boundary
 * Mailchimp_Integration draws around FNAME/LNAME/EMAIL merge fields.
