Replace the placeholder public key with the one whose private
counterpart is now held by the maximus-api license server. The old
key had no licenses issued against it (the server did not exist), so
no users are affected.
The 34 Rust unit tests still pass — license_commands tests use
ad-hoc test keypairs rather than the embedded one, and
embedded_public_key_pem_parses confirms the new PEM is valid.
