feat(intake): residence-type capture + CRM-owned inquiry emails for website cutover

Website register-interest form now offers the 3 residence types as a
multi-select; the choice + preferred-contact flow into the CRM inquiry
payload, the inbox detail, and the residential emails.

- inquiry inbox detail surfaces residence type(s), preferred contact,
  type-of-interest, comments (full data capture)
- residential-inquiry emails: client confirmation names the chosen
  villa(s); sales alert converted to the canonical detail-line format
  (uniform with berth/contact) + residence type(s)/preferred contact +
  plain-text part
- website-intake-fields parses residence_types[] + method_of_contact
- contact_form alerts split to their own recipient key
  (contact_notification_recipients)
- Residential Interests section: new residence_type field (schema +
  migration 0099, validators, inline select on the detail)
- contact-form-alert email refactor shipped (interest-alert style)

Tests: website-intake-fields, residential-inquiry templates,
contact-form-alert, residential-interest validators.
