This fixes LAND-1521 removing Talk and all associated code. It also removes the wayfinding button and moves the privacy notice and help and support options into the main app menu.

Targeting Brian's branch, but this should be merged to develop only after his branch goes to staging. This will ensure that people can get the deprecation message deployed to Talk first and then it will receive no other deploys.

Might want another set of eyes on the hoon changes, but this is looking good to me sans conflicts. Couple of very minor notes

Looks good! Some minor changes to copy and I feel like we ought to not no-op on analytics for the native app, that doesn't make much sense.
