Fix newest homepage detection, file creation dates, real IP, and request log visitor type

- Fix detectNewestPage() to search subdirectories recursively and handle language prefixes
- Fix getFileInfo() to preserve frontmatter created date or ctime instead of overwriting with mtime
- Automatically store created date in frontmatter when creating/editing files
- Add RequestLogger::getClientIp() with proxy and Cloudflare header support
- Replace domain column in request log with visitor/bot type badges (Human, AI, Search, Scraper)
- Update 'Activiteitenlog' to 'Activiteiten log' in UI and guide
