CAL-1006 Experiment: try dashboard as SPA vs SSR

Posted by @KATT

Heya :wave: come the [suspense](http://app.cal.com|app.cal.com> dashboard is server-side rendered? I feel it would feel faster if you did SPA there and you'd ship faster since it would unlock being able to use <https://trpc.io/docs/suspense) etc

Below is a almost 3s blocking request when toggling between "Availability" and "Booking"

Like, my suggestion would be to get rid of this stuff: https://github.com/calcom/cal.com/blob/8c150264f498b8e5d5cfedaebc69465c1dfd2aeb/apps/web/pages/availability/index.tsx#L121-L129

IIRC that stuff is there because of i18n-flicker, but I'm sure there's an alternative way of dealing with that

The main issue I'm seeing on this is that the page no longer updates the UI strings when changing your preferred language under Settings > General. This felt surprising to me, as I double-checked this workflow as part of my previous PR.

I checked out main and am seeing the same problem, so it's not necessarily related to this PR directly. I see there have been several commits relating to header cache since my PR. Might be worth spinning up an issue?
