refactor(cast): deduplicate browser wallet receipt handling in cast send

Extract `CastTxSender::print_tx_result()` to share the "print hash or
wait for receipt" logic between the normal send flow and the browser
wallet flow. Flatten the browser case into its own `else if` branch
so `--browser` takes priority over `--unlocked` instead of being
silently ignored.
