Release v0.2.0 (versionCode 2)

Webhook: Tickets 2026 form (customer_name title, voucher-name ticket
counting, ticketless ice/UTV orders, donor adult names); ice bag count
fix; voucher decrement; vendor webhooks; free kids through 12; multi-
origin lookup CORS; scanner Adults/Kids party panel + ice default 1.
First versionCode bump (was stuck at 1), so this installs over v0.1.0.
