Add tests for CSRF exclusions, Filter includeContent, multi-feed, and routing

- CSRF: test excluded paths (/api/login, /api/logout), PUT/DELETE methods
- Item model: test Filter includeContent flag, ItemById returns content,
  multiple feed_ids filtering
- API: test read_filter=all param, feed_ids comma-separated filter,
  full_content exclusion from stream
- Routing: add v3 frontend route test
