Enhanced OAuth2 API Tester tool, updated validation and improved CORS configuration:

- Improved OAuth2 Tester UI/UX: added support for multiple HTTP methods, query parameters, request body validation, collapsible result sections, and dynamic input handling.
- Enhanced `UserController` with validation annotations for `UserDTO` in API requests.
- Updated `UserDTO` to include stricter validation constraints (`@NotNull`, `@NotBlank`, `@Email`).
- Adjusted CORS configuration to allow all origins for OAuth endpoints.
