Subject: [PATCH] fix(web-ui): show error toast on non-JSON 4xx/5xx
 quick-action responses

In the catch block of all 11 hx-on:htmx:after-request handlers, check
xhr.status >= 400 and downgrade s to 'error' so a failed action that
returns an HTML error page (or other non-JSON body) surfaces as an error
toast instead of the optimistic 'success'/'info' default.
