Update dependencies and improve configuration management

- Updated LoLib dependency to version 3.0.0 in build.gradle.kts
- Added HikariCP and MySQL connector dependencies for improved database handling
- Enhanced jar minimization process to exclude JDBC pool and driver
- Refactored configuration management by introducing ConfigAccessor and ConfigLoader for better file handling and validation
- Removed deprecated GenerationOptions class and integrated its functionality into the new structure
- Improved command error handling and added cooldown hints for admin commands
