Remove stale "CSRF is disabled pending #524" note; update secFilter
description to reflect the enabled double-submit cookie pattern.
Add LoginRateLimiter and RateLimitProperties components with their
relationships to AuthService. Update frontend→secFilter rel to show
X-XSRF-TOKEN header.

Replace the stale Basic-Auth picture with the post-#523 model:
AuthSessionController + AuthService (the new auth/ package), Spring Session
JDBC (spring_session*, 8h idle timeout, fa_session cookie), and the
ChangeSessionIdAuthenticationStrategy bean used by login to defend against
session fixation. Addresses PR #612 / Markus M3.
