✨ Add improved abstraction for team permissions

Relevant changes:
- replace user-viewer? with can-edit removing many double
  negations on the code
- always use team permissions making the permissions access uniform
  around all the code
- expose team permissions to ui tree through ctx/team-permissions
  context
