chore(deps): bump Django, django-guardian, django-filter, drf-spectacular-sidecar

- django 5.2.17 -> 5.2.18 (security release: DoS fixes in language variant lookup and header parameter parsing, plus other security fixes)
- django-guardian 3.5.0 -> 3.5.2 (GHSA-5729-mvhf-9gq4: get_objects_for_user could return objects missing required permissions; also fixes global permission handling in get_objects_for_group and get_40x_or_None)
- django-filter 26.1 -> 26.2 (LinkWidget label escaping hardening)
- drf-spectacular-sidecar 2026.9.1 -> 2026.10.1
