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

<h1>Edge Proxy Relay</h1>
<p>Forward HTTP requests to any target server via the <code>x-relay-target</code> header.</p>
<h2>Endpoints</h2>
<div class="endpoint">
<h3>GET /health</h3>
<p>Health check. Returns <span class="status">200 OK</span> with server status, uptime, and version.</p>
</div>
<div class="endpoint">
<h3>GET /docs</h3>
<p>This page.</p>
</div>
<div class="endpoint">
<h3>Any Path (Catch-all Relay)</h3>
<p>Send a request with the <code>x-relay-target</code> header and this proxy forwards it.</p>
</div>
<h2>Usage — HTTP Relay</h2>
<pre><code>curl -s \\
-H "x-relay-target: https://httpbin.org" \\
-H "x-relay-path: /get" \\
"https://your-proxy.example/any/path"</code></pre>
