feat(license-minter): add cameleer-license-minter Maven module

Top-level module sibling to cameleer-server-core/-app. Depends on
cameleer-server-core for the LicenseInfo schema. Spring Boot
repackage produces a runnable -cli classifier for the vendor.

Not added as a dependency from cameleer-server-app — runtime tree
must not carry signing primitives.
