Replace Authorization Toggle by set-to-true and set-to-false.

By suggestion of @consideRatio in #183, we should think about and probably implement, replacing the authorization toggle (just set it to whatever it currently isn't) with a designated set-to-true and set-to-false to prevent potential shenanigans.

Start by reviewing issue #183 and locating the current authorization toggle implementation in the Python codebase. Replace the toggle behavior with explicit set-to-true and set-to-false operations, then verify that authorization can no longer be changed by inverting its current state.
