Walkthroughs and release of APKAM documentation for Noports

[XavierChanth]

Walkthrough an APKAM installation, fixing / addressing any issues we encounter along the way.

Things we should be able to do:

• Works e2e with a fresh pair of keys
• Multiple device APKAM installations works
• Secondary client with APKAM installation works

Giving a generous 5 SP to account for multiple walkthroughs + potential issues

Generic APKAM documentation for the widgets may also help with this documentation

I can merge the documentation, on APKAM now, but once this ticket gets closed I'd like to update the documentation to something easier.

Thoughts on making "activate your atsign" a subpage inside basic installation? We can put it in the prerequisites section of the installation.

Right now the installation page has 3 separate sections of different activations and honestly even I'm confused.

If we can separate the apkam enrollment and the atsign activation in the peoples brains I think we will have less confusion in the future,
