feat: add API key auth middleware for /api/* routes (task 3.1)

- Create src/middleware.ts with Next.js middleware
- Reads API_KEY env var and checks X-API-Key header on all /api/* routes
- Skips auth for /api/health endpoint
- Fails open (with warning) when API_KEY is not configured
- Returns 401 Unauthorized when key is missing or mismatched
- Mark task 3.1 as complete in tasks.md
