Replace matplotlib with pyqtgraph in Plot tab

- pg.PlotWidget (2×2 grid) with DateAxisItem for proper time axis
- Built-in pan (left drag), zoom (right drag / scroll wheel), Reset zoom button
- pg.InfiniteLine cursor with pg.SignalProxy for smooth 30 fps tracking
- Cursor value label shows nearest-point values colour-coded per trace
- Legend auto-updated via pi.legend.clear() + named plot() calls
- matplotlib removed from requirements.txt
