Collect leads with phone numbers, not just email

Until now, every lead form required an email address. Phone numbers can now be the lead contact too, and you decide exactly how to collect them:

• Phone-only forms: make phone the required contact and collect leads without asking for an email at all. Numbers are validated and stored in international format.
• Any combination: require email only, phone only, both at once, or leave both optional so visitors can submit with whichever they prefer.
• Managed in the field list: email and phone carry a Lead contact badge and are controlled with each field's Required toggle — no separate contact mode to configure. Every form keeps at least one contact field.
• Everywhere email leads go: phone-only leads appear in the Leads tab as the contact, are searchable by number, and flow through email notifications, Zapier, and the API just like email leads.
