Option to toggle autosave and add version control for production code

Currently, the autosave feature presents a risk when working with production queries and functions. If we accidentally modify code and forget about it, changes are automatically saved and no way to get them back. Right now I pull my schema and commit it every now and then but it's not most reliable option.

Proposed solution:
• Add toggle option for autosave on specific saved snippets
• Implement version control to track changes
• Allow reverting to previous versions when mistakes occur

This would greatly improve safety when working with production code while maintaining the convenience of autosave for development work.
