(core) add buttons to delete bad rules

Summary:
When access rules refer to tables and/or columns that no longer exist, offer convenient buttons to remove these rules.

It could alternatively be useful to generate errors when deleting tables or columns that are mentioned in access rules, and refuse to do so unless the access rules are updated first.

Test Plan: added and updated tests
