UI tweaks for East Sussex

See https://github.com/mysociety/fixmystreet-commercial/issues/641 and https://github.com/mysociety/fixmystreet-commercial/issues/642

Have already had feedback on these, and addressed some concerns.

You don't need moniker based things in a specific template.

Consider if even this behaviour could be achieved by including more specific templates in the parent, to help prevent forking issues. As this works fine without JavaScript (nice :) ), the parent template display might well be okay as the starting default?
