Missing {{ block.super }} in bottomimports blocks breaks custom overrides

Describe the issue

Several core templates override the bottomimports block without including {{ block.super }}.
This prevents customizations defined in base.html (via custom/templates/base.html) from being loaded consistently.

Examples:

• about.html → works, since it doesn't override bottomimports.
• latest-media.html (and others) → overrides bottomimports but does not call {{ block.super }}, so any global scripts/styles added in base.html are lost.

Expected behavior

All templates overriding bottomimports should include {{ block.super }} at the beginning of the block, e.g.:

{% block bottomimports %}
  {{ block.super }}
  <script src="{% static "js/latest.js" %}?v={{ VERSION }}"></script>
{% endblock bottomimports %}

This ensures global imports (e.g. custom scripts or styles injected via base.html) are preserved.

Steps to reproduce

1. Add custom/templates/base.html with a <script src=".../custom-sidebar.js">.
2. Visit /about → script is loaded.
3. Visit /latest → script is missing, because bottomimports was replaced.

Why this matters

Users rely on the documented override system (custom/templates/) to customize MediaCMS without patching the core.
If some templates drop {{ block.super }}, customizations become unreliable and inconsistent across pages.

Suggested fix

Audit all templates overriding bottomimports and prepend {{ block.super }}.
This makes the override system work consistently across the entire app.
