Update CI workflow to include hrn_tests coverage

Update the GitHub Actions workflow to include coverage for the new
hrn_tests feature across multiple build configurations.

This ensures that the DNSSEC override logic is validated in both
standard Rust and UniFFI-enabled environments. Including these flags in
CI prevents regressions where testing-specific code might break the
primary build or fail to compile due to type mismatches between the
LDK and FFI wrappers.

Testing both feature combinations (with and without UniFFI) guarantees
that the abstraction for HumanReadableName remains consistent across
all supported platforms and integration layers.
