Fix Dash static component collection in deployment

[Aberdur]

PR Description

This PR fixes Dash static asset collection during deployment.

Problem

The current Dash configuration includes dpd_static_support in PLOTLY_COMPONENTS, but that module is not installed in the deployment environment.

Because of that:

• collectstatic fails while loading Django static finders
• Dash component bundles are not collected into /static/dash/component/...
• some Dash apps load their backend routes correctly but render blank in the browser due to missing JS assets
