Replace Console Logging with Proper Logging Infrastructure

Problem

The codebase uses console.log/warn/error statements in production code:

• pages/blog.vue line 59: console.error('Blog fetch error:', err)
• server/api/blog.ts lines 53, 75, 79: Multiple console statements

Proposed Solution

• Implement structured logging with a proper logging library (e.g., consola, winston)
• Add log levels (debug, info, warn, error)
• Configure different logging for development vs production
• Add request tracing for API endpoints

Files to Update

• server/api/blog.ts
• pages/blog.vue
• Add logging configuration to nuxt.config.ts
