build(applet): enable int support in CAP converter

M2D.2 introduced StructuralCbor.encodeUint(int,...) and call sites
in DeviceResponseBuilder that pass int literals. The JC converter
rejected this without an explicit ints="true" attribute, breaking
both j3r180 and j3r452 CAP builds since 9879668.

ant-javacard's <cap ints="true"> opts the package into JCRE int
support. The CBOR encoders need it to handle uint values up to
2^32-1 per RFC 8949.
