🔒 Implement concurrency protection and remove marketing text

- Add analysisInProgress useRef to prevent multiple simultaneous analyses
- Protect all analysis entry points (performAnalysis, quickAnalyze, etc.)
- Update button disabled state to include concurrency check
- Remove marketing text from analysis page and AIAnalysisPanel
- Fix remaining TypeScript compilation errors in chart components
- Ensure clean UI without promotional content

Fixes sync issues caused by overlapping analysis sessions
