E2E Playwright Testing (#466)

* Add e2e testing for frontend

* Hopefully working CI/CD for playwright

* Fix run name

* Trying to fix the CI/CD stuff

* Try this again, although Vite apparently has playwright?

* Fix vitetest

* Add registration tests

* Safer kill of testing dependencies

* These might not last.

* feat: Add iPhone and Android device testing

* fix: Minor fixes, set registration to "fixme" as it fails frequently for some reason.

* fix: Make sure the OS dependencies get installed

* fix: For now remove mobile, they seem to be very hit or miss.

* Use sharding based testing

* Fix some minor mess ups

* Forgot PNPM for the merge
