- Create apps/web/lib/phone.ts with VN_PHONE_REGEX, normalizePhone, formatPhone, and zaloHref helpers - Deduplicate phone regex: auth.ts and inquiry.ts now import VN_PHONE_REGEX from @/lib/phone instead of defining their own local patterns - Replace raw .replace(/^0/, '84') in inquiry-detail-dialog.tsx and lead-detail-dialog.tsx with zaloHref(); use formatPhone() for display Resolves GOO-209 Co-Authored-By: Paperclip <noreply@paperclip.ing>
