Cookie consent banner improvements

[pi0]

• Position can be fixed to reduce CLS (CLS optimization #21)
• We can show it earlier to reduce LCP (LCP optimizations #45)

Some other ideas (to be implemented if we go by module approach):

• Respcting do-not-track
• Lazy loading banner component when does not needs to be displayed

I expect artifact of this issue (other than fixing in nuxt-movies) can be a nuxt module for implementing SSR-friendly cookie and probably an blog article to mention tips

We can also SSR render banner but I'm not sure if it violates EU rules or not to keep consent cookie in cookies. cookiebot for instance is doing this so assume it is compliance. /cc @addyosmani

Just to check, is the ask whether we can SSR render the banner if we need to check cookies in order to tell whether the banner needs to be hidden or not?

[pi0]

Yes. We can make use of a cookie know consent status universally. Just wanted to ensure this is okay :)
