feat(vision): add the configurable HTTP vision provider

Registers an OpenAI-compatible chat-completions provider into
ctx.imageRecognition with a user-editable baseURL + API key via a settings
section and the credential plane. Logs the secret-free vision request body
as the image-recognition/llm-request session event.
