Radar axes: one canonical order everywhere

The dashboard fingerprints sorted score dimensions alphabetically
while the ticker page rendered them in API order, so the same ticker
drew a differently-shaped polygon on each page.

New shared helper radarAxesFromDimensions() pins the axis order to the
backend's DIMENSIONS list (technical, sr_quality, sentiment,
fundamental, momentum; unknown dimensions append alphabetically) and
centralizes the label truncation. Used by the dashboard fingerprint
strip, the ticker header radar, and ScoreCard.
