vibeqr - VietQR-compatible QR image API with ZaloPay native support

GET /image/<BANK_ID>-<ACCOUNT_NO>-<TEMPLATE>.svg?amount=<vnd>&addInfo=<code>&accountName=<name>

Templates: qr_only, compact, compact2 (replicating the VietQR templates).
Formats: svg (png planned). Every code encodes a hybrid payload:
the ZaloPay native wallet block plus the VietQR bank block,
so ZaloPay users pay natively and bank apps pay as a transfer.
Single-account service: path bank/account segments are accepted
for VietQR compatibility and ignored; all codes pay the owner.
