Test MAS addresses against real Postfix; close MAS-WP-0002, add MAS-WP-0003

Browse source 
- experiments/postfix-probe: Postfix 3.7 -> pipe -> mas-gateway -> ticket
  service in Docker; 14 address forms x 5 configurations. 13/14 arrive
  byte-identical everywhere; quoted "ticket=PR42" is unquoted in transit.
  Legacy bang/percent rewrites never fire for MAS addresses.
- docs/experiment-review.md: Email infrastructure section with results
- MAS-WP-0003: provider-side live test on a real subdomain (needs DNS/MX)
