fix: resolve durability and combat issues with stackable items

- Updated database schema to set stackable items as non-stackable.
- Implemented migration script to convert existing stackable items to instances with durability.
- Fixed combat logic to ensure players lose if no weapon is equipped.
- Added admin commands for inventory debugging and resetting.
- Enhanced item display to show durability instead of quantity.
- Conducted thorough testing and validation of changes.
