Refactor item property parsing and centralize utility functions

- Moved `parseItemProps` function to `core/utils.ts` for reuse across modules.
- Updated various services to import and utilize the centralized `parseItemProps`.
- Introduced new utility functions for handling consumable cooldowns and healing calculations.
- Enhanced mob management with a new repository system, allowing for dynamic loading and validation of mob definitions from the database.
- Added admin functions for creating, updating, listing, and deleting mobs, with validation using Zod.
- Implemented tests for mob management functionalities.
- Improved error handling and logging throughout the mob and consumable services.
