This explains every "nothing happens" report you've had — FAQ, search icon, and now login — they were never separate bugs. It was one thing the whole time: JavaScript wasn't allowed to run at all in your dev server.
One more thing worth doing once this works: open your browser's console (F12 → Console tab) on any page and check for red CSP errors. If you see any, paste them here — that'll mean there's a second spot needing the same kind of fix (e.g. if you later add a third-party script or font from another domain, it'll need to be explicitly allowed in that same CSP list in middleware.ts).
