Security console has no safeties against multiple runs

[mikron-ia]

The security console commands (rbac/*) can be ran any number of times, and the only safeties that prevents repeated runs from causing a mess are database integrity constraint violation checks - hardly a pretty or reliable solution.

Add a simple migration-like system on this mechanism:

• Check whether any given rbac/* command was ran via a database table
  • If it was, report this and do not run it again
  • If it wasn't, run it and note that

This does not entail any rollbacks or anything like this - this is a simple safety system, not a complete system.
