fix: 替换 e.printStackTrace() 和 System.out.println 为 logger 调用

- HttpProxyVerticle: err.printStackTrace() / e.printStackTrace() -> LOGGER.error()
- RouterHandlerFactory: 5处 printStackTrace() -> LOGGER.error()
- CommonUtil: e.printStackTrace() -> LOGGER.error()
- ReflectionUtil: 新增 LOGGER，3处 printStackTrace() -> LOGGER.error()
- CreateDatabase: e.printStackTrace() -> LOGGER.error()
- URLUtil: 新增 LOGGER，e.printStackTrace() -> LOGGER.error()
- LzTool: e.printStackTrace() -> log.error()
- MkwTool: 3处 System.out.println + 1处 printStackTrace -> log.debug()/log.error()
- PdbTool: e.printStackTrace() -> log.error()
- ParserApi: t.printStackTrace() -> log.error()
- CacheManager: 2处 Throwable::printStackTrace -> LOGGER.error()
- QQTool: 3处 System.out.println -> log.debug()
- FjTool: System.out.println -> log.debug()
