Fixed: Query Tool database access permissions

[v 1.0.0] – 2025-03-05

🔒 Security Fixed

• Database access restriction: Corrected an issue where the Query Tool was able to access databases outside the one it was configured for.
• Permission enforcement: Resolved a security flaw that allowed users to view or query tables from other databases, ensuring access remains limited to the intended scope.

⚡ Improved

• Access control: The Query Tool now strictly enforces database isolation, preventing unintended access to additional databases.
• Security compliance: Strengthened validation logic to block any unauthorized cross-database visibility or querying.

📋 Technical Details

• Issue: The Query Tool could list or access database names and tables beyond its assigned database.
• Verification: Confirmed through user reports indicating visibility of unrelated databases at the query interface level.
