/**
 * Creates the Express application for the HTTP MCP server.
 *
 * Auth: clients send `Authorization: Bearer <token>` where <token> is either
 * a static API key or an OAuth access token. The token is forwarded as-is to
 * the FFmpeg Micro API, so the MCP server never needs to know which kind it is.
 *
 * OAuth: Per the MCP spec, the MCP server acts as the authorization server from
 * the client's perspective. OAuth endpoints are proxied to the API gateway
 * (api.ffmpeg-micro.com) which handles the actual OAuth logic. The client only
 * ever talks to mcp.ffmpeg-micro.com.
