Subject: [PATCH] Annotate Api::Problem error with thiserror::transparent

Error variant `Api::Problem` prints "API error: {problem}" however the Problem struct has display impl that starts by printing "API error". Together this results in "API error: API error" followed by the details.

This fixes that by annotating `Api::Problem` with `thiserror`'s `transparent` attribute which forwards the display impl to the underlying types display impl.
