fix(studio): Qt6 compat + Ctrl+C signal handler

- flash_console: setTextFormat(Qt.TextFormat.RichText) — int overload removed in Qt6
- installer_widget: same fix + add Qt to QtCore import
- project_editor/installer_widget: Session.has() → Session.can()
- app.py: signal.signal(SIGINT, SIG_DFL) so Ctrl+C kills the process from terminal
