feat: add context window and pricing columns to evals database

- Added contextWindow, pricePerMillionInputTokens, and pricePerMillionOutputTokens columns to runs table
- Updated OpenRouter models hook to fetch and cache full model data including context and pricing
- Enhanced UI to display context window and pricing information in runs list and details pages
- Generated database migration for new columns
