Fix Modal overlay + per-slot template preview dropdown

- Modal: revert to inline styles (Tailwind fixed class broken).
  Added max-height: 80vh with overflow-y: auto for scrollable content.
- Template configs: preview is now per message slot via dropdown
  (assets added/removed/renamed/deleted, periodic, scheduled, memory)
  instead of hardcoded to assets_added only.
