Refactor and Enhance Stream and Event Services

[aalamu]

Description

This pull request refactors and enhances various aspects of the stream and event services to improve code quality, consistency, and maintainability. Key changes include moving shared logic to StreamService, adding localization, updating DTOs, and enhancing the live broadcast functionality.

Key Changes

1. Refactoring and Code Consolidation

• Moved common and shared implementations to StreamService to reduce code duplication.
• Added final modifiers to variables and method parameters to enforce immutability where applicable.

2. Relocation of Converter Classes

• Moved converter classes (ToTitleCase.java, ToLowerCase.java, ToUpperCase.java, ToUpperCaseConverter.java, ToLowerCaseConverter.java, ToTitleCaseConverter.java) to API-Service to centralize and better organize these utilities.
• Relocated BaseAdapter.java to API-Service for consistency.

3. Localized Responses

• Localized responses such as SignOutResponse to improve support for multiple languages.

4. Updates to DTO and Response Classes

• Renamed DTO and response classes for clarity, including updating UpdateEventVisibilityDto to UpdateEventOrStreamVisibilityDto and other related changes.
• Created new DTOs and response classes for live broadcast and stream features, including LiveBroadcastRequest which serves as a base class for live broadcast-related requests.

5. Enhancements to Live Broadcast Services

• Introduced LiveBroadcastUpdateService to handle asynchronous interactions with YouTubeLiveBroadcastService.
• Enhanced LiveBroadcastServiceImpl with core implementations derived from LiveBroadcastService.

6. Updates to Method Signatures and Static Methods

• Updated method signatures in EventServiceImpl to be static where appropriate, reflecting their usage.
• Added final modifiers to method variables and parameters for better code consistency and to prevent unintended modifications.

7. Documentation and General Refactoring

• Added documentation to various classes and methods to enhance code clarity and maintainability.
• Performed general code refactoring and improvements to streamline code and remove redundancies.

8. Custom HTTP Response Status

• Added FleenHttpStatus for customized HTTP response statuses, allowing for more precise control over HTTP responses.

9. Localization and Message Updates

• Updated localization message files (messages_en_US.properties and messages_fr.properties) with new keys and translated responses.
