Allow any orientation for PWA

[opentree27]

Hey, love the project. It's been my main use ever since getting a smart trainer.

I've been using it as PWA on my android for simplicity on my samsung tablet. I've seen that in the manifest.webmanifest orientation is hardcoded to portait ->"orientation": "portrait". Can this be changed to "any"? It would make much more sense for people with larger displays.

Thanks!
