Fix TradingView indicator CI tests

[Mathieu2301]

Summary

• Make TradingView dataCompressed parsing more tolerant of base64 variants and non-zip compressed payloads.
• Prevent compressed strategy report parsing failures from surfacing as unhandled rejections in study updates.
• Reduce indicator test flakiness by running the authenticated SuperTrend/MarketCipher tests sequentially and increasing the SuperTrend timeout.
• Run Vitest explicitly with --run in GitHub Actions.

Validation

• npm test -- --run ✅
• npx eslint src/protocol.js src/chart/study.js ✅
