feat(admin): ask the panel to restart, from verdande's own settings

A container cannot replace its own image from the inside, so "update" is really "ask whoever owns the container to recreate it" — Yggdrasil pulls `:latest` on the way, which is what makes a restart an update at all. This removes the second browser tab, not the panel's authority: the panel still does the work and still records who asked. Three settings, needed together, and the page names whichever are missing — an operator reading "not configured" should not have to go and find out which of three. The token is never sent to a browser; the page is told only whether it is set. Answers 202 rather than waiting. The panel stops this container as part of answering, so the reply may never arrive, and a request cut off mid-flight is the successful case wearing a failure's clothes. The interface believes neither answer and polls /healthz until it responds. Administrators only, and sessions only. A leaked API token that could restart the server is a denial of service in one request. Co-Authored-By: Claude Opus 5 <[email protected]>
