feat: replace docs placeholder with interactive test page across all entry points

Browse Source 
- Replace router.ts handleDocs static placeholder with full interactive test page
- Replace worker.ts handleDocs with interactive test page
- Remove dead handleDocs() from index.ts (route already serves public/test-api.html)
- Update public/test-api.html with proper model defaults (deepseek-v4-flash-free)
- Add cache_control system prompt field to Anthropic test card
- Update handleIndex() to link to Interactive Test Page
- Remove handleDocs tests from index.test.ts
