Resolve, claim_show, and claim_list_mine return different claim signatures

Nobody has claimed this yet.

Specifically, the `category` field is missing from resolve, but there may be other differences.

Start by reproducing the outputs from the `resolve`, `claim_show`, and `claim_list_mine` commands shown in the issue, then trace how each command constructs its claim response. Compare the returned fields and make the claim signatures consistent, with tests or command output demonstrating that the fields match.
