fix: scrape pause threshold load>10 \u2192 load>50 (consistent with auto-orchestrate)

domain-scrape-loop was still using the old aggressive 'load>10 pause 30s'
threshold while auto-orchestrate raised to 50. HF Space normal load is 10-15.
Result: scrape kept pausing every iter even though container was healthy.

Now both daemons share threshold load>50 = real saturation only.
