fix(rpm): preserve config on upgrade, set correct ownership/permissions

RPM packaging improvements:
- Fix %config(noreplace) directive in spec file (logcorrelator.yml)
- Fix post script: use correct path for .yml.example (/etc/logcorrelator/)
- Set /var/run/logcorrelator ownership to logcorrelator:logcorrelator
- Set correct permissions: /var/run (755), /var/log (750), /var/lib (750)
- Add %config(noreplace) for logrotate.d/logcorrelator
- Add comprehensive RPM test script (packaging/test/test-rpm.sh)

Documentation updates:
- Update architecture.yml with filesystem permissions section
- Document socket ownership (logcorrelator:logcorrelator, 0666)
- Document config file policy (%config(noreplace) behavior)
- Add systemd hardening directives (NoNewPrivileges, ProtectSystem)
- Update ClickHouse schema: mark non-implemented fields
- Remove materialized view SQL (managed externally)
- Add stdout sink module documentation

Build pipeline:
- Update Dockerfile.package with comments for config policy
- Add /var/lib/logcorrelator directory creation
- Document fpm %config(noreplace) limitations
