Move (basic) recovery functionality to webnative

[expede]

...and then presumably consume this in the Dashboard

This stage can be “merely” a root key+UCAN download (no BLS yet)

Tasks

• Move (simple variant of) recovery kit to webnative

Added dependencies label, as recover functionality makes use of device linking, which would need to be put into webnative first.
I.e. depends on #305

@matheus23 thanks for listing the issue dependency! Good info to capture 👍

I removed the dependency label because it's about dependencies for the package:

[dependencies] Pull requests that update a dependency file

I also went ahead and stack-ranked the issues in the milestone: https://github.com/fission-suite/webnative/milestone/4

@walkah feel free to rearrange them over there! The project list doesn't have the ability to easily rearrange yet 🤷‍♀️
