feat: Add Lombok @Getter and @Setter annotations to reduce boilerplate code in multiple classes (#4321)

# Description of Changes

Update classes across the codebase to use Lombok's `@Getter` and
`@Setter` annotations, replacing manually written getter and setter
methods. This change streamlines the code, reduces boilerplate, and
improves maintainability.
