Portal UI "Learn More" -> "Show Origin"

[djat]

Portal front end, change "Learn More" to "Show Origin", which will do a dynamic web service call to a sawtooth http wrapper that will retrieve the blockchain written transaction based on passing a ID (DID) for the emission or pledge record.

Initially this will be a hard coded API key, next phase is replacing with client side magic link/wallet.

The "Source File" (csv or xls for example), both originally downloaded (and the URL of the download source and the organization that published it), and any modified version (i.e. changes of date formatting for import into database or system), author(s), last modified date.
