refactor: move fallback error templates to shared directory with improved naming

Reorganize error template structure to consolidate shared templates in a dedicated location. Changes: - Move templates/fallback/* to templates/shared/ with -fallback suffix - 404.html → 404-fallback.html - 500.html → 500-fallback.html - generic.html → generic-fallback.html - Update error_renderer.py to use new template paths - Modified template selection logic in _find_template() - Updated documentation strings to reflect new paths - Update error rendering documentation - HTML_ERROR_RENDERING_FLOW_DIAGRAM.md: Updated diagrams and examples - ERROR_RENDERING_DEVELOPER_DOCUMENTATION.md: Updated file structure and paths Benefits: - Clearer organization with all shared templates in shared/ directory - Consistent naming convention (-fallback suffix) indicates purpose - Aligns with existing cdn-fallback.html in same directory 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
