ImportJobRawflag silently dropped at plan-build time — SHOW RAW behaves as SHOW (pkg/parser/ast/dml.go:3209, pkg/planner/core/planbuilder.go:3498, pkg/executor/builder.go:930, pkg/planner/core/operator/logicalop/logical_show.go:61)

can we merge the rule with above, so we can decode RAW as optional
below "RAW" "IMPORT" "JOBS" too

Refactored this into helper nonterminals in parser.y so both SHOW RAW IMPORT JOB <id> and SHOW RAW IMPORT JOBS reuse the same optional-RAW structure without introducing parser conflicts. Updated in 0aac5bb.
