PR Summary

• Added new MSSQL workflow file A new file named .github/workflows/mssql.yml has been added.
• Renamed workflow to db-mssql The name of the workflow has been updated to db-mssql.
• Modified workflow triggers Removed on: [push] and added on: workflow_call: with defined input parameters. This allows the action to be used as an external dependency and avoids code duplication across repositories. The input parameters have their default values and descriptions to guide users when calling this action from another YAML file.
