fix(freight-api): quote fallback sort aliases

Sorting by a column with no explicit sortExpr fell back to the bare
select alias unquoted. Postgres folds unquoted identifiers to lowercase,
so any camelCase alias (utilizationPct, bookedTons) 42703'd. Quote the
fallback to match the case TypeORM's addSelect actually emitted.
