fix: support string values in additionalAuditDimensions

Book rules used string dimension names (e.g. "规则一致性") but
buildDimensionList only accepted numeric IDs, silently dropping
all custom audit dimensions. Now resolves strings via reverse
lookup against DIMENSION_MAP with fuzzy matching fallback.
