Add GraphQL dataloaders for batched record lookups

Introduce dataloadgen-based dataloaders to batch individual
record-by-ID fetches in GraphQL resolvers into single SQL
queries. Each entity type (organization, framework, control,
vendor, document, risk, measure, task, file, report, profile)
gets a LoadByIDs method in coredata and a GetByIDs service
method with variadic arguments and dedicated collection return
types. Resolvers now use dataloader.FromContext instead of
direct service calls for single-record lookups.
