Subject: [PATCH] fix: HTML export tojson filter + authenticated file download
 (v0.14.1)

- Enable minijinja 'json' feature so the tojson filter is available in
  the Memories.html template (was causing 'unknown filter' render error)
- Replace window.location.href downloads with fetch+blob so the
  Authorization header is sent (window.location.href caused 401)
