Subject: [PATCH] fix: omit empty expiry from PIS connect payload

The form submits an empty expiry when the field is left blank, which was
passed through as `expiry: ""`. With fintecture-client >= 2.5.x this is
forwarded to meta.expiry, and the API rejects it (406:
"$/meta/expiry must match pattern ^[0-9]+$"). Falling back to undefined
when blank omits the field entirely, matching the simulator's handling.
