Cut metered-proxy bandwidth: re-sweep floor + wire-size logging

JobQueue now skips bands swept within MinResweepHours (config, default 6h) instead of re-scraping the whole catalogue continuously — the dominant cost on the metered residential proxy. Roughly linear savings with no data loss (full pagination retained); 0 disables it. Worker logs the real compressed transferSize per job (what the proxy bills) rather than the ~6.5x-larger decompressed length, so spend is visible.
