SECURITY: Enforce recipient PM allowlists for existing direct chat channels [backport 2026.1] (#41926)
Backport of #41923 to release/2026.1.

---

## Summary

Correctly enforce the PM allowlist preference
(`enable_allowed_pm_users`) when an excluded user attempts to send a
message in an existing one-to-one direct message channel. Previously,
the Guardian helper did not check the allowlist, allowing excluded users
to continue sending messages after the recipient enabled the
restriction. The fix integrates `UserCommScreener` into the recipient
authorization check, also preventing thread creation and updating user
card chat availability accordingly.
