Refactore scenes

[Mosch0512]

This pull request undertakes a significant refactoring of the game's core scene management and utility functions. By extracting various functionalities from a single, large source file into multiple specialized files, the changes aim to enhance modularity, improve code maintainability, and establish a clearer separation of concerns. This architectural improvement will facilitate easier development, debugging, and future expansion of game features.

Highlights

• Scene Modularization: The monolithic 'ZzzScene.cpp' file has been broken down into several dedicated scene files: 'LoginScene', 'CharacterScene', 'MainScene', 'WebzenScene', and 'SceneManager', significantly improving code organization.
• Camera Functionality Extraction: All camera-related logic and variables have been moved from 'ZzzScene.cpp' into new, specialized 'CameraUtility.cpp' and 'CameraUtility.h' files.
• Common Utilities Consolidation: Shared utility functions, including abuse filters, text processing, audio controls, and rendering helpers, have been extracted into 'SceneCommon.cpp' and 'SceneCommon.h' for better reusability.
• Server Port Update: The default game server port 'g_ServerPort' has been updated from '44406' to '55902' in 'ZzzScene.cpp'.
• New Character Account Limit Constant: A new preprocessor definition, 'MAX_CHARACTERS_PER_ACCOUNT', has been added to '_define.h' to explicitly define the maximum number of characters per account.
