style: weitere flutter-analyze Infos beheben

Ungenutzte Imports (dart:typed_data, flutter/services.dart), unnötige
String-Interpolations-Klammern, führender Unterstrich bei lokaler Funktion,
fehlende Blockklammern bei if-Statements und SCREAMING_CASE-Konstanten in
clipboard_image.dart auf lowerCamelCase umbenannt. Rein mechanisch, keine
Verhaltensänderung.
