      summary: Run the accessibility fix agent on a page
      description: Resolves the page identifier to a live URL, URI and host id, mints a short-lived token for the calling user, and forwards the request to the configured a11y agent service. Returns the agent's report once the run completes. This call is synchronous and a full run can take minutes - use /fix/stream to receive progress as it happens. Requires the dotPageScanner-config App to carry the agent url and auth token.

      summary: Run the accessibility fix agent, streaming progress over SSE
      description: Same as /fix, but relays the agent's Server-Sent Events as they arrive rather than waiting for the run to finish. Frames carry the run id, phase steps, progress counts, heartbeats, and a terminal done, aborted or error event. A configuration failure is reported as an SSE error frame rather than an HTTP status, because the response has already begun.

      summary: Stop an in-flight accessibility fix run
      description: Cooperatively stops the run identified by runId. The agent stops at its next safe checkpoint and the open /fix/stream connection receives a terminal aborted event carrying a partial report - fixes already applied are kept. Runs are addressed by runId rather than by caller identity, because the proxy mints a fresh token per request.
