Reformat every module with autopep8 and hand-tune the remaining long lines so that `flake8` passes with default settings (max line length 79). No behavior changes: long f-strings, messages, QSS/Textual CSS rules and argument lists are only wrapped or split, an unused import and an unused local are dropped, and dbus-next D-Bus signature annotations carry targeted `# noqa` comments.
