Fix several frontend bugs

[itaisteinherz]

This fixes some bugs in the frontend app:

• The menu drawer doesn't contain any navigation buttons.
• The Knowledge home button doesn't always navigate to the homepage.
• When running a search, the search input stays focused and doesn't get blurred.
• The footer credits are off on mobile devices.

Not sure on the next dev script though: what exactly it does?

It should be the same as next, but works a bit better for me. It basically starts the Next.js server and runs your app, as well as watches for code changes and does hot-reloading.
