Layout v2 template fixes: style blocks and heading levels

- inbox.html, admin_all_mail.html: move <style> block into {% block head %}
  (styles outside Jinja blocks are silently dropped in template inheritance)
- feedback.html, feedback_detail.html, feedback_new.html, user_settings.html:
  replace <h1 class="h4"> with <h2> to match app-wide heading convention
