pick from https://github.com/apache/doris/pull/67621 Problem Summary: FE tracks tablet activity with per-tablet sliding windows, consuming substantial heap and retaining stale entries on followers and observers. Use BE query and load counters to report bounded sets of active tablets. Replace FE sliding windows and asynchronous recording with per-BE report snapshots, and rank query and load activity separately for cloud balancing. Also fix inflated tablet counts when cloud tablet reports retry. Reduce FE memory usage for tablet activity tracking. Rename `WindowAccessCount` to `AccessCount`, reflecting activity over a BE report interval. Tablets outside the reported top-N show zero activity. ### What problem does this PR solve?
