Get Paged Agent Runs

Paginated agent runs for the admin agent runs dashboard.

The window is the absolute half-open interval [from_time, to_time). The dashboard sends the UTC instants for the edges of the operator's local calendar days, so filtering to one past day means that day in their timezone -- the boundaries cannot be inferred from a bare date here. A naive value is read as UTC.

An omitted or empty agent_types / status / company_ids means every value on that axis.

The /runs endpoints below still take from_date/to_date date strings, and so still carry the UTC-offset skew this signature removes; they back a different dashboard and were left on the old contract deliberately.
