fix: use unique names for chart series

[yonasuriv]

What

Fixes duplicate React key warnings and a radar chart data-loss bug caused by getShortName() collapsing every model in a family to a single name.

key={entry.name} collided when a family had more than one model (Claude ×3, Gemini ×3, MiniMax ×2, Grok ×2), producing "two children with the same key" and dropping points in the radar chart. getShortName() now keeps the full model name for multi-model families ("Claude Opus 4.7" vs "Claude Fable 5") while leaving single-model families untouched.

Also widens the CostEfficiency Y-axis so the longer labels fit.

Test plan

• pnpm run check and pnpm run build pass
• All 16 model series in results-with-skills.json and results-without-skills.json map to unique chart names, no duplicates

Greptile Summary

The PR updates chart naming to preserve distinct series for model families containing multiple models and gives the cost-efficiency Y-axis more room for the resulting labels.

• Normalizes model names and retains full names for Claude, Gemini, Grok, and MiniMax series.
• Preserves abbreviated labels for currently single-model families and versioned GPT labels.
• Widens the cost-efficiency chart’s Y-axis from 60 to 95 pixels.

Confidence Score: 5/5

The PR appears safe to merge, with the current model set producing unique chart identifiers and the wider axis accommodating the longer labels.

The naming change removes existing family-level collisions across all current model inputs, while downstream chart keys and radar data identifiers receive distinct values.

Important Files Changed

Filename	Overview
src/components/charts/chartConfig.ts	Revises model-name normalization so all current chart series remain unique without introducing a reachable failure in the committed model data.
src/components/charts/CostEfficiencyChart.tsx	Widens the Y-axis to accommodate the longer labels produced by the naming fix.
