The kiosk previously ran a debounced background lookup on every keystroke
in the visitor Email/Phone fields, silently autofilling matches. Replaced
with a dedicated "Look up existing account" field that only searches when
the operator presses Enter or clicks Search, and matches exactly against
either email or phone (never both from one query, to avoid digits in an
email being misread as an unrelated phone number). Also simplified the
"account already exists" banner wording.
