Introduce common dependency to centralize configuration and shared code

[duylv27]

There are currently many duplicated configuration classes (e.g., SecurityConfig, CorsConfig, RestClientConfig, etc.) within the config package across multiple services, as well as utility classes like AuthenticationUtils, CustomAuditingEntityListener, etc.

We propose introducing a new dependency, tentatively called common-service (name to be discussed), which will centralize these shared configurations and utilities. This way, all services can utilize the common code.

Thanks, and I look forward to discussing further.
