Issue: Add Soft Delete Functionality for Snippets

Description
Instead of permanently deleting snippets, implement soft delete support. Deleted snippets should be recoverable from a trash/recovery section, ensuring users can restore accidentally removed content.

Acceptance Criteria

• Add isDeleted (boolean) flag in snippet schema
• Snippets marked as deleted should be excluded from normal queries
• Create a trash/recovery section to list deleted snippets
• Allow users to restore deleted snippets from trash
• Ensure activity logging captures delete and restore actions
