fix: add proper locale detection and URL parsing to 404 page

- Add detectLocaleFromURL helper function to extract locale from URL path
- Handle both params-based and URL-based locale detection
- Make params optional since it's undefined when 404 is triggered
- Use regex to extract locale from URL path (e.g., /en/page -> en)
- Remove debug logging and clean up imports

Note: Currently falling back to default Next.js 404 due to layout component issues
