fix: enforce 32-digit numeric EID validation with inline user feedback

EID input now strips non-numeric characters, shows a digit counter warning
while typing, and enforces exactly 32 digits via Zod schemas across domain,
order configurations, and order selections layers. Also installs missing
input-otp dependency.
