Move I/O provider abstraction to ui-console, add ledger/account/problem DTOs

InputProvider/OutputProvider were api-layer types only ever implemented
by the console UI; relocate them there. Drop the unused
GuessMarketEngine/LocalGuessMarketService pair, flesh out LoadResultDTO
with success/failure variants, and make LocalGuessMarketContext.LoadAsync
report real outcomes instead of an empty placeholder.
