(core) respect table wildcard in granular acl rules for censorship

Browse Source 
Summary:
The client relies on metadata tables for laying out pages and sections.
These tables are filtered according to what tables the user has access
to, in a crude way.  This diff updates the logic to at least support
the table wildcard.

Test Plan: added tests
