Summary:
AccessRules class that implements that UI is intended to look vaguely like
detailed rules might look in the future, but only supports the very limited set
we have now.
In addition, UserManager and BillingPage code is separated into their own webpack bundles, to reduce the sizes of primary bundles, and relevant code from them is loaded asynchronously.
Also add two TableData methods: filterRowIds() and findMatchingRowId().
Test Plan: Only tested manually, proper automated tests don't seem warranted for this temporary UI.

Summary: This moves enough server material into core to run a home server. The data engine is not yet incorporated (though in manual testing it works when ported).
Test Plan: existing tests pass
