Pratik Mankawde d2cefa05d9 fix(telemetry): make the load generators fail loudly instead of exiting 0 ...

Three ways a run could produce no traffic and still report success:

- tx_submitter logged a funding shortfall and returned an empty stats object;
  main() then printed the summary and exited 0, so the failure only surfaced
  later as "spans missing", which points nowhere. It now records setup_failed in
  the summary and exits 1 after the report is written.
- --weights was checked for valid JSON but not for a positive sum. An all-zero
  mapping reached random.choices, which raises ValueError from inside the
  dispatch loop where only CancelledError is caught. Rejected at parse time now,
  in both generators.
- a profile phase declaring neither rpc nor tx logged a warning and returned no
  error. Both error rates short-circuit to 0.0 when nothing was sent, so a
  mistyped key produced zero traffic and still passed the exit gate. That phase
  is now an error.
