fix(intercept): destructive commands score high; chunk batch decisions to the server limit

The destructive shell signal is worth 60 instead of 50, so a destructive command alone scores 10 + 60 = 70, high. The level thresholds are unchanged. The approvals page sends the selection in sequential calls of at most 100 ids, the server limit (maxBatchDecide), instead of one call that the server would refuse with 400 when more than 100 rows are selected. If a call fails, sending stops: its ids and the later ones stay selected with the error, and ids already decided stay decided. The final toast gives the totals.
