Add internal/services/membership package: AttendanceLoader, TransactionLoader, ExceptionLoader interfaces + NewStubSources stub (returns ErrIOPending until M4 lands real Sheets loaders). FeesReport and ReconcileReport orchestrate domain/fees + domain/reconcile and write fixed-width text reports matching Python calculate_fees.py and match_payments.py print_report output. 13 unit tests cover all formatter branches and orchestration wiring via fake loaders. cmd/fuj/main.go: fees and reconcile subcommands now dispatch; sync/infer retain the [M4] placeholder.
