refactor(tests): merge detect_suggested_procedure into expected_detection

Two overlapping TestTemplate fields (expected_detection: narrative
guidance from imports/leads; detect_suggested_procedure: concrete
commands from approved suggestions) are now one. Blue-side procedure
suggestions target expected_detection directly, appending onto
whatever is already there rather than overwriting it — same
merge-not-overwrite behavior already used for the red side. Existing
detect_suggested_procedure data is folded into expected_detection
before the column is dropped.
