This PR is handles the changes required to support envelopes. The new
envelope editor/signing page will be hidden during release.

Even though Documents and Templates are removed, from the user
perspective they will still exist as we remap envelopes to documents and
templates.
This pull request updates the implementation of the admin leaderboard,
enhancing data handling and improving type safety. It introduces clearer
differentiation between users and teams, adds additional fields to track
more relevant information, and refactors the querying logic to optimize
performance and maintainability.
Improves the existing document rejection process by actually marking a
document as completed cancelling further actions.
