What changes are proposed in this pull request?

Makes the "MLflow Demo" experiment visually distinct from regular experiments in the experiment list:

  1. Description: Sets mlflow.note.content tag on the demo experiment during generation, populating the Description column with a helpful summary.
  2. Demo badge: Replaces the plain experiment name with a clickable turquoise "MLflow Demo Experiment" badge (Tag component) in the Name column. Includes a ? icon with a tooltip explaining the demo and how to clean it up from Settings.
  3. Pinned to top: Demo experiment is always sorted to the top of both the full experiment list page and the home page "Recent Experiments" section via client-side reordering.

Demo detection uses mlflow.demo.version.* tags (already set by the demo generator framework), avoiding fragile name-based matching.

How is this PR tested?

  • Manual tests

Manually verified:

  • Demo experiment shows at top of experiment list with turquoise badge and ? tooltip
  • Demo experiment shows at top of home page recent experiments
  • Description column shows the demo description
  • Clicking the badge navigates to the experiment page
  • Non-demo experiments render normally
