fix(gateway): wrap cron helpers with staticmethod to prevent self-binding

Plain functions imported as class attributes in APIServerAdapter get
auto-bound as methods via Python's descriptor protocol.  Every
self._cron_*() call injected self as the first positional argument,
causing TypeError on all 8 cron API endpoints at runtime.

Wrap each import with staticmethod() so self._cron_*() calls dispatch
correctly without modifying any call sites.
