Auto-detect whether the user entered an email or phone number.
Email sends via Resend, phone sends via Twilio SMS. Users table
has nullable phone and email columns; verification_codes uses a
generic identifier field.

Replace email-based auth (Resend) with phone-based auth (Twilio SMS).
Add BBQ_FEATURES env var for toggling features at deploy time — when
auth is disabled, no login routes are registered and the app works
as before.
