fix(wallet): await on-chain confirmation before returning from deploy-program

The DeployProgram command previously submitted the transaction and
immediately returned success, even if the sequencer rejected it. Now it
polls get_transaction_by_hash until the transaction appears in a block,
exiting non-zero with a clear error message after a 30s timeout.
