warmup: grow main (trucking) pool faster -- 3k -> 4k/day now, 5k at day 14

Browse source 
The main sending IPs are cleanly warmed: today 3,845 sent at 0.18% bounce,
ZERO deferrals, ZERO ISP rate-limit/blocklist/Spamhaus hits. The script's own
note records these IPs historically sustained ~2,500/day at 68-76% delivery;
collapses only ever came from 17k-29k spikes. So we have ample headroom to
accelerate the trucking ramp safely:
  day 7-13: 300/h -> 400/h (~4,000/day)   [applied now, day 8]
  day 14+:  new    500/h    (~5,000/day)   [hard ceiling, well under ~17k]

Also vendored pw-listmonk-rampcap into the repo (infra/postfix/) -- it
previously lived only on the server at /usr/local/bin. Live script updated and
applied (listmonk cap now 400/h).

#!/bin/bash
# Ramp the Listmonk hourly send cap (sliding window) in lockstep with the
# Postfix IP warmup, so newly-rotated sending IPs are not blasted.
#
# Driven off the SAME warmup start date as pw-mta-warmup
# (/etc/postfix/pw-warmup-start). Accelerated schedule, justified by historical
# mail.log data showing these IPs cleanly sustained ~2,500 sends/day at 68-76%
# delivery once warm; collapses only ever came from 17k-29k spikes.
#
# Target STEADY-STATE total daily volume (cap is per-hour; ~daily/10 active hrs):
# day 0-1 : ~500/day -> 50/h
# day 2-3 : ~1,500/day -> 150/h
# day 4-6 : ~2,500/day -> 250/h
# day 7-13 : ~4,000/day -> 400/h (IPs cleanly sustained 2.5k+ at 68-76%
# delivery; 0 deferrals/blocks observed)
# day 14+ : ~5,000/day -> 500/h (hard ceiling; never blast past ~17k where
# historical collapses began)
