fix: use text/html;profile=mcp-app MIME type for MCP Apps resources

The ext-apps spec requires RESOURCE_MIME_TYPE (text/html;profile=mcp-app)
for hosts to recognize resources as MCP Apps. Without the profile parameter,
Claude Desktop/web fails with "Failed to load MCP App: the resource may
exceed the 5 MB size limit."
