Backfill slicing. The sync workflow caps at 500 pages of 50 (25k
transactions) per run and now throws rather than silently truncating, so
the backfill parent fans the range out across child runs that each stay well
under that ceiling. A 7-day slice absorbs ~3.5k transactions/day before it
would trip. Both are workflow args, so a slice that does trip is retunable at
run time rather than in code.
