feat: show debug banner on testnet or debug mode, add TESTNET tag (#143)

Display the red debug banner when on a testnet OR when DEBUG is enabled.

When on a testnet, a "TESTNET" label is shown on the far right side of the banner. The banner label shows the network name when not in debug mode, and "DEBUG / INSECURE" when debug is on.

closes #140
