warmup: ROLL BACK main pool to 200/h after Gmail spam-blocked IPs at 400/h

Browse source 
Day 9 (2026-06-13) alert: main pool 54% delivery, 202 Gmail spam-blocks
(550-5.7.1 'Gmail has detected') on warming IPs .94-.98. The 4k/day (400/h)
ramp was too aggressive AND the trucking pool lacks the per-MX throttling the HC
pool got -- Google-Workspace-hosted business domains (weberfarms.net, uatruck.com,
etc.) concentrated and Gmail blocked us. Held at 200/h (~2k/day) through day 20 to
recover, then slow step to 300/h. Applied live (cap already set to 200/h).
