Update credit class metadata UI when C04 metadata gets fixed

[blushi]

Is your feature request related to a problem? Please describe.
The C04 credit class metadata currently deployed on chain has some incorrect RDF uses in it / could be simplified.
The front-end is currently set up to support that so it displays correctly in the UI for now but once the metadata is fixed, we should update the front-end too to reflect those changes.

Describe the solution you'd like

• We might want simplify regen:bufferPoolAccounts to be just a list, see ruuts-c04-metadata regen-registry-standards#57 (comment) and relavant code in regen-web: feat: Credit Class Page "Additional Info" improvements #1980 (comment)
• Within regen:bufferPoolAccounts, we use regen:walletAddress but this should be regen:address, see ruuts-c04-metadata regen-registry-standards#57 (comment) and feat: Credit Class Page "Additional Info" improvements #1980 (comment)
• We should check for schema:Duration equality for parsing duration values: feat: Credit Class Page "Additional Info" improvements #1980 (comment)
