[Medium impact] The PR appears safe to merge; no new blocking issue remains.

Summary

The PR redesigns the navbar, search field, and cluster switcher for desktop and mobile. Since the last review, it removes the search input fade and documents and tests which name survives when saved endpoints share a URL.

• The navbar rearranges search and site links to fit the screen.
• The cluster menu brings built-in and saved RPC endpoints into one place.
• The search dropdown gives filters and results a clearer layout.
• Test setup clears saved browser data between test cases.
