refactor: switch block prod test to mixed UTxO backends

Update the block production test to use mixed UTxO backends ("mem" and
"disk") instead of mixed P2P/legacy topologies. The test now records
the backend type in the database and test output, and the helper
script sets the MIXED_UTXO_BACKENDS environment variable accordingly.
