The bundled township tool (supervisord [program:township]) launched without
-c/--config, so a township_config.json bind-mounted via --map into
/cache/township_output was never read — the web UI came up with blank API key /
league upload credentials / options every restart.

* supervisord: pass --config /cache/township_output/township_config.json so a
  mapped config auto-loads. Map the bare-metal dir with
    coderai-docker --map /path/to/township_output:/cache/township_output
  and the saved settings + credentials come up automatically.
* gen_township_fighters.py: a MISSING --config file is no longer fatal (fresh
  install with no mapped dir) — fall back to defaults and start normally; a
  malformed config still errors. The web UI's Save already writes back to
  <out-dir>/township_config.json, so first-run saves persist into the mapped dir.

Bump version to 0.1.4.
