feat(inventory): introduce stock deficit notifications and base quantity tracking

- Added `quantity_base` field to reservation model for precise inventory calculations
- Implemented non-blocking stock deficit warnings during kit creation process
- Enhanced API responses with warning details for frontend display
- Updated terminal interface to show formatted stock shortage alerts

BREAKING CHANGE: API response structure now includes `warnings` array instead of previous stock warning format
