Dark Mode: make a testable WebUIDataSource for unit tests

There was no easy way to get at the set load time data keys/values nor
the $i18n{} placeholder strings.  My upcoming work for dark mode
requires a key be set whether or not dark mode is enabled or on.

I'm adding TestWebUIDataSource in hopes that it's more generically
useful, as TestWebUI has been.
