Add Comprehensive Analysis endpoint to WebApp

[Copilot]

Implements the high-priority Comprehensive Analysis feature (analyze/comprehensive-analysis CLI command) in the WebApp. This combines market data, news/sentiment, technical analysis, fundamental analysis, risk assessment, and AI-powered recommendations into a single endpoint.

Changes

New API Controller

• ComprehensiveAnalysisController: GET /api/ComprehensiveAnalysis/analyze?symbol=AAPL&assetType=stock
  • Orchestrates multi-source analysis via ComprehensiveStockAnalysisAgent
  • Sanitized error responses, detailed logging

Service Registration

• NewsScrapingService, CompanyValuationService, MarketSentimentAgentService, ComprehensiveStockAnalysisAgent
• Explicit type checking for YahooFinanceDataPlugin dependency injection

Configuration

• appsettings.json.template provides API key structure (OpenAI, Alpaca, AlphaVantage, FMP, Google Search)
• Made configuration files optional to allow server start without secrets
• appsettings.json gitignored for security

Bug Fixes

• Fixed pre-existing HTML syntax errors in StatisticalAnalysis.razor (malformed div, incomplete td)

Usage

curl "http://localhost:5000/api/ComprehensiveAnalysis/analyze?symbol=AAPL"

Returns comprehensive analysis text combining all data sources. Requires API keys configured in appsettings.json (copy from template).
