Add datetime return annotations to both helpers.

ANN202 is enabled and not ignored. Annotate _month_start_boundary() and its nested async _q() with -> datetime.

helper functions, _month_start_boundary() and its nested async _q(), with a
datetime return type to satisfy ANN202; keep their existing behavior unchanged.

Use past-dated fixtures for finalized sessions. The billing query includes every session with started_at >= month_start and ended_at IS NOT NULL; it has no upper bound against NOW(). These fixtures can therefore count future-dated sessions as finalized billing data.
