refactor: Centralize build paths for Android and iOS

Centralized build paths for Android and iOS by moving them into dedicated configuration objects within `FastlaneConfig`. This improves code organization and maintainability.

- Moved Android build paths to `FastlaneConfig::AndroidConfig::BUILD_PATHS`.
- Moved iOS build paths to `FastlaneConfig::IosConfig::BUILD_CONFIG`.
- Updated Fastfile lanes to use the new centralized paths.
