ui: rename "Open in OpenWebUI" to "Swiss AI Chat", reorder buttons

- Button text "Open in OpenWebUI" → "Swiss AI Chat". The underlying URL
  still points at the OpenWebUI deployment, but users see "Swiss AI Chat"
  which matches the surface-level brand they actually interact with.
- Reorder so Metrics Dashboard (secondary, emerald) sits left of Swiss
  AI Chat (primary, black). Both still right-aligned as a group; the
  primary action lands at the right edge where the eye finishes scanning
  the card.
