fix(mysql): enable window function parsing for data export sql_type

[LordofAvernus]

User description

Fixes actiontech/sqle-ee#2987

Summary

• Enable parser.EnableWindowFunc(true) in MySQL splitter so SELECT with OVER(...) parses as SelectStmt instead of UnparsedStmt
• Add unit tests for window function DQL classification and SQLE00082 coverage
• Fixes data export export_sql_type=ddl misclassification blocking workflow submit
