Pull Request Overview

This PR reopens previously disabled unit tests by removing TODO comments and uncommenting test code related to stream functionality. The changes systematically re-enable test coverage that was temporarily disabled for stream-related features.

• Uncommented test cases across multiple test files in the planner and parser libraries
• Restored test functionality for various SQL operations including GROUP BY, SELECT, ALTER, and stream-related commands
• Updated mock catalog and message type definitions to support the re-enabled tests

• The table name has been changed from "t1" to "stream_t1". This renaming should be consistent throughout the codebase to avoid breaking references to the original table name in tests.

    ITableBuilder& builder = mcs->createTableBuilder(db, "stream_t1", TSDB_NORMAL_TABLE, 3, 0)
