fix(46-04): right-align header controls, clean up ControlPanel model display

- FloatingNodeHeader: Controls (comment, expand, run) now sit flush-right
  against the node edge with tighter spacing.
- ControlPanel: Remove "Model" label. Model name sits directly under the
  settings title, separated by a horizontal divider.
- Add new-tab link icon next to provider name that opens model details page.
