Feat(adev): faster initial loading + iPad availability of the playground

[mauriziocescon]

Describe the problem that you experienced

I’m currently trying to play with angular on my iPad during a short vacation. Unfortunately, I can’t cause "the environment is not supported"… on the other hand, I’m totally capable of doing it with Svelte / Vue / Solid.

I must admit the overall experience of Svelte / Vue / Solid playgrounds on an iPad is quite amazing! 😅

I guess there’s some room for improvements for adev: initial loading performance and iPad (tables) support for occasional usage.
