Guard prints, fix pointer access, adjust color

Wrap debug prints with kDebugMode (imported from flutter/foundation) in EventEmitter, Menu, and TrayIcon so logging only occurs in debug builds; add an ignore_for_file for prints in the example. Fix FFI pointer indexing in Preferences and SecureStorage by using pointer arithmetic ((keysPtr.value + i).value) instead of elementAt. Adjust Window.backgroundColor conversion to compute RGBA from normalized components (r/g/b/a * 255) with rounding and clamping. Also remove the default visual-effect fallback mapping.
