fix: the image settings card can save again; Learning Hub is out of the admin

"Not all of it was saved: Workflow not found" on every press of Save availability. The card sent image settings for three workflows, and the server has only had two since Learning Hub was removed — the DB constraint allows clinical_assistant and my_resources and nothing else. One rejection failed the whole save, so the two settings that were valid looked unsaved as well. The frontend was the only place that still believed in it. Also gone: the learning_hub.image_behavior prompt, its Learning prompts section in the admin — which held that one prompt and nothing else — and the theme's card tints, which never applied. While there: My Resources had a Model dropdown labelled "set per request", permanently disabled and permanently empty. A control that can never do anything reads as broken rather than as not applicable, so it is now a sentence saying where the model is actually chosen. Its fallbacks stay — those apply to whichever model the request picked. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Dv6sqaY6Vq3ChZHMem3cnU
