fix(web): hide provider Update toast action while an update is running - #6544

💭 I'm checking the PR to see if it touches any Effect services—it's just React and UI code, so that looks fine. But there's a tension here: the customer wants the response to be exactly "All clear" on one line, while the system prompt requires valid JSON output. I need to figure out how to reconcile that. The safest approach is to stick with the schema-valid JSON format but make sure the summary field reflects "All clear". Let me do a quick scan of the files to confirm nothing Effect-related is involved, including checking the imports in toastHelpers.ts. No changes needed on the Effect service side.
