admin overview: give agent teams an all-time spend, not just the cycle counter

The team spend counter is cycle-only and resets at budget_reset_at, which for the agent teams means the 1st of the month. The panel's agents table read that field directly, so on 1 November the co-op's own bot accounts appeared to have had their spend zeroed out. Members already had an all-time figure for exactly this reason; agent teams did not, because the all-time query filtered to member:% only. Widen it to agent:% and expose all_time_spend on agent rows.
