Overhauled Proposal-list endpoint to serve all Proposals that the requester can see
Does not complete STT-1266.
Changed only the default behavior; if parameters are supplied, the old behavior is preserved. A tech debt story will be created to address this difference.
Also:
- Added Proposal repo methods to list by user_id via Author and SR
- Added Authors to TDG Proposals that lacked them
- Created service
get_and_anonymize_proposals_for_user
, an easier-to-use, more general wrapper aroundanonymize_proposals
