Move error handling inside main loop to survive bad cycles

A failed trading cycle (e.g. sell rejected after close) previously
propagated to the top-level .catch() and process.exit(0), killing
the container permanently. Now errors are caught per-iteration so
the bot sleeps and retries on the next cycle.
