[OTHER] Refactor project to use Lombok annotations for boilerplate reduction

[kuntal1461]

📝 Description

Many classes in the project currently contain manually written boilerplate code such as:

• Getters and setters
• equals(), hashCode(), and toString() methods
• Constructors for simple field initialization

This can be simplified and standardized using Lombok annotations, improving maintainability, readability, and consistency across the codebase.

---

🎯 Goal

Refactor all eligible POJOs, DTOs, entities, and configuration classes to use appropriate Lombok annotations such as:

• @Data — for full getter/setter + equals/hashCode/toString
• @Getter / @Setter — for selective accessors
• @NoArgsConstructor, @AllArgsConstructor, @Builder — for simplified instantiation
• @Value — for immutable objects

---

💡 Proposed Approach

1. Identify target classes:
   Locate classes with repetitive accessor/mutator methods.

2. Refactor incrementally:

   • Replace manual boilerplate with Lombok annotations.
   • Retain custom logic or overridden methods (e.g., validation in setters).

3. Ensure consistency:

   • Use project-wide coding conventions for annotation placement and imports.
   • Verify no conflict with existing serialization/deserialization frameworks (e.g., Jackson).

4. Update documentation:

   • Add Lombok dependency and usage notes in README.md or CONTRIBUTING.md.

---

✅ Benefits

• Significant reduction in code verbosity.
• Improved readability and maintainability.
• Easier onboarding for new contributors.
• Reduced risk of human error in repetitive methods.

---

🧪 Acceptance Criteria

• All relevant classes refactored to use Lombok.
• Build and test suites pass without regressions.
• Lombok dependency verified in pom.xml / build.gradle.
• Documentation updated to reflect Lombok usage.
