feature(SqlLoader): transformations in SqlLoader

[scaliseraoul]

• Tests added and passed if fixing a bug or adding a new feature.
• All code checks passed.

---

Important

Enhance SQLDatasetLoader to apply transformations using TransformationManager and add corresponding tests.

• Behavior:
  • SQLDatasetLoader in sql_loader.py now applies transformations using _apply_transformations() after executing SQL queries.
  • Removes redundant _apply_transformations() from local_loader.py.
• Transformations:
  • TransformationManager in transformation_manager.py now directly uses Transformation objects for applying transformations.
• Tests:
  • Adds test_sql_loader.py to test SQL loading and transformation application.
  • Removes SQL-related tests from test_loader.py.
• Misc:
  • Updates VirtualDataFrame in virtual_dataframe.py to use SQLDatasetLoader for data loading.

• Draft comment:
  The apply_transformations method now uses a Transformation object instead of a dictionary for transformations. This change improves type safety and clarity.

  The format parameter was renamed to _format to avoid conflict with the built-in format function. This is a good practice to prevent potential issues.

• Draft comment:
  The load method no longer reinitializes self.query_builder. This is a good change as it avoids unnecessary reinitialization.

  The new functionality in SQLDatasetLoader is well-covered by the added unit tests in this file. Good job on ensuring the new code is tested!
• Reason this comment was not posted:
  Confidence changes required: 0%
  The code changes in the PR include modifications to the SQLDatasetLoader class, which is part of the library code. The PR also includes new unit tests for the SQLDatasetLoader in a separate test file, ensuring that the new functionality is tested. This aligns with the requirement that new code should have corresponding unit tests.

  Ensure that the SQL queries are parameterized to prevent SQL injection vulnerabilities. Consider using parameterized queries or ORM features to handle this.
