run_with_label piped output through a while loop, so $! tracked the
formatter PID instead of the actual command. Ctrl-C killed the formatters
but left app/worker/css-watch running as orphans. Switch to process
substitution so $! is the real command PID, and pkill -P children before
killing tracked PIDs.

setup_paddle.py creates a notification destination in Paddle and writes
the webhook secret + setting ID to .env. dev_run.sh resets the DB, seeds
data, and starts an ngrok tunnel to update the webhook URL automatically
for end-to-end checkout testing.
