Thanks for the PR :)

I spotted one issue so far.

Clicking on a group produces an 404 error because /access/groups/{user_group_id}/roles doesn't exist, groups are associated with a role when a new ACE is created.

Just noticed that groups haven't been modified yet. Should I just merge this PR and the rest will come in other PRs?

This is the SQL model for the RBAC system, I thought this may help you to see how things are related to each other.
