Add comprehensive test coverage for new optimizations

Added 21 new tests covering critical areas:

**New test file: test_sitemap_and_utilities.py (13 tests)**
- Sitemap exists and returns valid XML
- Sitemap performance (<1 second generation)
- Sitemap URL count (under 50k limit)
- Sitemap contains critical URLs
- Sitemap excludes individual verse URLs
- Sitemap caching works
- Robots.txt configuration
- Health check endpoint

**Extended test_web_routes.py (8 tests)**
- Story routes (index, kids, detail pages)
- Story counts caching
- Markdown rendering with Mistune
- Resource slug index lookups (O(1) optimization)
- Invalid slug 404 handling

Test suite: 110 → 131 tests (100% passing)
Coverage: sitemap (SEO critical), stories, markdown, resource slugs
