style: gofmt currency conversion files

Apply gofmt to files touched by the currency conversion port. Fixes
struct-field alignment (Querier/ViewQuerier/CurrencyConverter in
QueryService), import grouping order (pkg/currency alphabetized
before pkg/customcost), and a trailing whitespace introduced by the
original PR.

No behavior change.
