TGC-796: Allow dynamic summaryPath config for back links

[davidatdefra]

Proposed change

Allow pages that extend SummaryPageController to override getSummaryPath to specify a url path to use when returning from the "Change" action. Will fallback to using the existing /summary hardcoded path if getSummaryPath is not implemented.
