justin 03223dfd6c Rename project to OBDash + per-metric colored multi-axis 
Rename: the app is vehicle-agnostic, so 'ford-obd' was wrong. Rebranded all
code/docs/profile authors to OBDash; Gitea repo renamed justin/ford-obd ->
justin/obdash (remote + description updated). Ford the make and the
ford-6.0-powerstroke profile are unchanged (that vehicle really is a Ford).

Multi-axis upgrade (per request):
- MultiAxisPlot now gives each METRIC its own Y axis, each axis colored to
  match its line; the primary metric owns the LEFT axis, others stack right.
- Click a line to promote it to the left axis (sigClicked -> set_primary).
- Cleaner teardown (no removeItem warnings); axis label no longer doubles the
  unit; Normalize round-trips.

Validated headless: colored per-metric axes, promote-to-left, gauge view,
normalize toggle, profile switch; obdcore + diagnostics tests pass.

V8 with two banks: dual-bank fuel trims and pre/post-cat narrowband HO2S included. CAN-era PIDs (0142 module voltage, 0146 ambient, 0133 baro, 012F fuel level) not supported and omitted. No verifiable manufacturer-enhanced (mode 22) PIDs for this EEC-V SCP vehicle; generic ELM327 adapters widely reported to fail enhanced sessions on Ford SCP PWM. All reliable data is in the standard SAE J1979 mode-01 set. Validated: all formulas safe-evaluator-clean; fuel-trim vmax normalized to +-100."
