Diagnostics: removed the always-on right-side Diagnostics dock (it ate screen
space on every view). Read Codes now opens a modal dialog listing codes
grouped stored/pending/permanent with descriptions (no-start codes bold red);
Clear Codes keeps its confirmation, and on re-read pops a dialog only if codes
returned. Dropped the View > Show Diagnostics Panel toggle.
Gauges: replaced the plain progress-arc with a proper automotive dial -- round
face + bezel, major/minor tick marks, a numeric scale (rounded labels), a red
needle + center hub, a colored rim arc for the value, and an amber peak tick.
Digital readout + name/unit below.
Validated headless: no Diagnostics dock; Read Codes opens the Trouble Codes
dialog; gauge view renders. obdcore + diagnostics tests still pass.

gui/widgets.py:
- MultiAxisPlot -- overlay with one Y axis PER UNIT (psi/V/rpm/C/%), linked
ViewBoxes on X, so mixed-scale signals are readable at true values
(base left axis + up to 4 right axes).
- SinglePlot -- one shared axis for the Normalize (% of range) mode.
- ArcGauge -- 270deg arc gauge with peak tick + numeric readout, own dark bg.
- GaugeGrid -- scrollable grid of gauges.
gui/main.py:
- Graph page is now a multi-axis/single-axis sub-stack; Normalize toggles
between true multi-axis (raw) and single-axis (%). curves map key->color;
plot ops route to the active graph widget.
- Gauge View menu enabled (3rd center page); gauges update on tick with peak.
- Theme applies to both plot widgets; profile switch clears graphs/gauges.
Fix: ArcGauge QPen built via setCapStyle (the QPen(...cap=...) kwarg segfaults
PySide6). Validated headless: driving preset -> 6 unit groups across 5 axes,
gauge view renders, normalize round-trips, profile-switch clears cleanly.
obdcore + diagnostics tests still pass.
