fix(components): make MiniBar and MiniLine tolerate malformed series data

[yyqdbngt]

Summary

• MiniBar and MiniLine now tolerate non-array data props (rendered as empty / nothing) and drop non-finite elements (NaN/Infinity) before scaling
• Replaced Math.max(...data, 1) / Math.min(...data, 0) spreads with loops so a very large series cannot hit the call-argument limit
• Adds regression tests: MiniBar.test.tsx (non-array data, NaN elements) and a new MiniLine.test.tsx (non-array data, <2 finite values, NaN excluded from the path)

Why

Both shared mini-chart components read data.length and spread data into Math.max/Math.min without validating the array. A non-array payload (e.g. null/undefined from a malformed wire response) crashed the whole component tree at data.length, and a single NaN element poisoned max/min, producing NaNpx bar heights / NaN SVG path coordinates that silently broke the chart. The dashboard trend column passes the raw throughput array from the API straight in, so the component itself must be defensive even where a call site adds its own guard.

Testing

• ./node_modules/.bin/vitest run src/components/__tests__/MiniBar.test.tsx src/components/__tests__/MiniLine.test.tsx src/pages/home/__tests__/DashboardPage.test.tsx → 13 passed (5 new; verified all 5 fail with the pre-fix components)
• ./node_modules/.bin/tsc --noEmit → clean
• ./node_modules/.bin/eslint src/components/MiniBar.tsx src/components/MiniLine.tsx src/components/__tests__/MiniBar.test.tsx src/components/__tests__/MiniLine.test.tsx → 0 errors

Summary

Makes MiniBar and MiniLine tolerate malformed series data by filtering non-array inputs and non-finite values. Solid defensive fix — prevents NaN/Infinity from poisoning chart rendering.

Findings

• [Info] MiniBar.tsx:27 — The Number.isFinite filter is the correct guard; alternatively Number.isNaN + explicit Infinity check would also work but isFinite is cleaner.

Suggestions

No blocking issues. Good test coverage for edge cases.
