"""Tests for the geo cache flush background task.
Validates that :func:`~app.tasks.geo_cache_flush._run_flush_with_resources` correctly
delegates to :meth:`~app.services.geo_cache.GeoCache.flush_dirty` and only logs
when entries were actually flushed, and that
:func:`~app.tasks.geo_cache_flush.register` configures the APScheduler job
with the correct interval and stable job ID.
