Refactor testing to use new TableDB schema

Added TableDB schema for testing purposes, including table definitions for 'customers', 'users', 'address', and 'employees'. Updated tests to utilize TableDB instead of Northwind for schema consistency in the specs. Adjusted file permissions setup in the workflow to accommodate the new test database. Included .vscode directory in .gitignore for local environment isolation.

Enhances test database structure clarity and modularity.
