fix: logger race

- Refactor logger using sync.Once to improve performance
- Initiate log setup in a goroutine to prevent blocking
- Integrate gin.DefaultErrorWriter and gin.DefaultWriter for logging
- Introduce request ID generation for better request tracking
- Simplify setup logic by removing redundant variables and code
