Upgrade PyQt5→PyQt6, numpy v1→v2, Python 3.8→3.12, all dependencies

[Copilot]

Migrates Inlinino from PyQt5 to PyQt6 (and numpy v1 to v2), updating all dependencies to current stable versions compatible with Python 3.12 on Windows, macOS, and Linux.

Dependency Updates

• PyQt5→PyQt6 6.7.x, pyqtgraph 0.12.1→0.13.7 (PyQt6 support, _generic template suffix)
• numpy 1.22.x→2.2.x, scipy 1.9.x→1.15.x
• wakepy 0.7.1→1.0.x, kaleido 0.2.1→1.x, plotly 5.13.x→6.x
• pynmea2, pyusb, hidapi bumped to current releases
• Python: ==3.8.* → >=3.12,<4 in setup.py and CI workflow

PyQt6 Migration

QtMultimedia — QMediaPlaylist/QMediaContent removed in Qt6; replaced with QSoundEffect:

# Before (PyQt5)
self.alarm_playlist = QtMultimedia.QMediaPlaylist(self.alarm_sound)
self.alarm_playlist.addMedia(QtMultimedia.QMediaContent(QtCore.QUrl.fromLocalFile(f)))
self.alarm_playlist.setPlaybackMode(QtMultimedia.QMediaPlaylist.Loop)

# After (PyQt6)
self.alarm_sound = QtMultimedia.QSoundEffect()
self.alarm_sound.setSource(QtCore.QUrl.fromLocalFile(alarm_files[0]))
self.alarm_sound.setLoopCount(-1)  # infinite

Widget class namespaces — In PyQt6+pyqtgraph 0.13.7 QtGui no longer contains widget classes; all moved to QtWidgets: QMainWindow, QDialog, QApplication, QMessageBox, QFileDialog, QDialogButtonBox, QSplashScreen, QPushButton, QSpacerItem, QWidgetItem, QLayoutItem.

Fully-qualified enums — PyQt6 dropped unscoped enum access:

# Before
Qt.WindowModal / QMessageBox.Warning / QSizePolicy.Expanding
# After
Qt.WindowModality.WindowModal / QMessageBox.Icon.Warning / QSizePolicy.Policy.Expanding

Other API changes:

• exec_() → exec() throughout
• setFilterRegExp → setFilterRegularExpression; QVariant() wrapping removed
• QPalette.Window → QPalette.ColorRole.Window
• QTextCursor.End → QTextCursor.MoveOperation.End
• logging.getLogger('PyQt5') → 'PyQt6'

wakepy 1.0 API

Old functional API (set_keepawake/unset_keepawake) replaced with context manager:

self._wakepy_mode = wakepy.keep.running()
self._wakepy_mode.__enter__()   # on start
self._wakepy_mode.__exit__(None, None, None)  # on finish

PyInstaller

Hidden imports updated from *_pyqt5 → *_generic (pyqtgraph 0.13.7 ships backend-agnostic compiled templates).
