feat(app): register film and song renderers via plugin system

Create film-renderer.ts and song-renderer.ts as RendererDefinition
plugins using defineAsyncComponent for lazy loading. ContentPanel.vue
now looks up film/song components via getRendererForContentType()
instead of direct imports, enabling future community renderer plugins.
