♻️ refactor: Refactor API endpoints to use dynamic API prefix from environment variables

- Updated all service files to replace hardcoded API paths with `${import.meta.env.VITE_API_PREFIX}` for better configurability.
- Ensured consistency across user, common, and gateway services by applying the new API prefix format.
- Removed unnecessary comments and maintained ESLint disable directives where applicable.
