FN-6939: add narrow dock preview modal
Adds an accessible preview modal path for constrained Dev Server right-dock layouts.
- Detect narrow direct right-dock hosts while preserving inline previews for full-page, mobile, and expanded modal hosts.
- Replace the crowded inline preview with a compact Open preview launcher and accessible modal controls in narrow docks.
- Add focused preview/mobile coverage, documentation, styling, and a published package changeset.
