Adds a `customer_phone` column on events plus an `event_phone_field_enabled`
admin setting (default off) that surfaces the input in the create-event
and event-detail forms. Designed for downstream automation tooling — once
exposed via the upcoming public API, n8n / similar can pick it up to
deliver gallery links over WhatsApp, SMS, etc.
- Migration 080 adds the column + seeds the setting as false. Existing
deployments see no UI change unless the admin opts in via
Settings → Events.
- Backend strips the field server-side when the toggle is off (defence
in depth against form bypass).
- Frontend renders the input only when the public-settings flag is true;
always optional even then.
- publicSettings + EventSettings types extended; CreateEventPage and
EventDetailsPage wired to read the toggle and submit the value.
