[BR19] Too big method initComicCollectionPage()

[alisina97]

The initComicCollectionPage() method in the ComicRepositoryPanel class is too long and complex, which violates the Single Responsibility Principle (SRP) and makes the code harder to understand and maintain. Impact: Decreased readability: Large methods are harder to understand and navigate, especially for new developers or during code reviews. Maintenance issues: Changes or updates to the functionality of this method can be challenging and error-prone due to its size and complexity. Recommendation: Refactor the initComicCollectionPage() method into smaller, more focused methods that handle specific responsibilities. This will improve code organization, readability, and maintainability.
