MAS-WP-0004: Postfix integration profile, corpus probe in pytest, Exim notes

Browse source 
Profile in integrations/postfix (install.sh + README), now used by the
live deployment. Probe runs every conformance-corpus local-part and the
relay negatives against it; tests/test_postfix_profile.py runs it where
Docker is available.

Check whether Exim has equivalent pitfalls for `!`/`%` local-parts and
record the needed settings. Build an Exim profile only if there is
demand.
## Outcome
- Profile: `integrations/postfix/install.sh` and `README.md`. The live
deployment (`deploy/railiance/entrypoint.sh`) now uses it.
- Probe: `probe.py --profile mas-profile --corpus`, run in pytest as
`tests/test_postfix_profile.py` where Docker is available. Every corpus
address arrives unchanged up to RFC 5321 quoting: Postfix adds quotes
around non-dot-atoms (`.bernd` becomes `".bernd"`), and those are still
invalid MAS. All relay negatives get 554.
- Exim: `integrations/exim/NOTES.md`. The stock ACL rejects `!`/`%` for
local domains. No profile is built, because there is no demand yet.
