Benedikt Willi fab66d1528 Implement Jinja2 templates for startpage and error pages
Features:
- Add Jinja2 template engine for page rendering
- Create startpage with Bowser branding and version info
- Create error page templates for 404, 500, and network errors
- Support for about:startpage special URL
- Custom error message support in templates
- Graceful fallback rendering if template fails
- Browser now starts with startpage when no URL provided

Templates:
- assets/pages/startpage.html - Beautiful purple gradient intro page
- assets/pages/error_404.html - Pink gradient 404 error page
- assets/pages/error_500.html - Red gradient 500 error page
- assets/pages/error_network.html - Orange gradient network error page

Code:
- src/templates.py - Template rendering utilities with Jinja2
- Updated main.py to use startpage as default
- Updated Frame.load() to handle about: URLs and render errors with templates
- Added 7 comprehensive template tests

All 62 core tests passing (excluding GTK-dependent tests)
