fix: Details button opens full-screen node detail on desktop (#778)

The previous fix (#779) used hash navigation for the Details button,
which only re-selected the node in the side panel on desktop. Now the
Details button calls showFullScreenNode() to render the same full-screen
detail view that mobile users see, regardless of screen width.

- Extract showFullScreenNode() from mobile-only init code
- Reuse it for both mobile init and desktop Details button click
- Analytics links still navigate via hash as before
- Update Playwright test to verify full-screen view renders
