Refactor server configuration management

- Removed old server configuration files (server.json, server.log, server_config.c, server_config.h).
- Introduced a new configuration file (server.conf) with a more structured format.
- Implemented a configuration parser (config_parser.c) to read and apply settings from server.conf.
- Updated server logic to utilize the new configuration structure.
- Enhanced logging functionality and added rate limiting features.
- Improved error handling and security measures in request processing.
