Add email field to RSVP edit form with automatic confirmation

- Added email_address field to RSVPEditForm interface and form
- Email field is required and positioned after name field
- Added helper text explaining new confirmation will be sent if email changes
- Updated form validation to include email as required field
- Backend now detects email changes and sends new confirmation emails
- Email field follows same editing rules as other fields (disabled when event closed)
- Updated backend to use email_address parameter instead of attendee_email for consistency
