Admins opt into admin powers via an on-page switch instead of only
?admin=true. The toggle renders ONLY for users the server reports
can_elevate, reusing each tool's existing header placeholder (or
creating one) and floating it bottom-right via fixed positioning.
Admin mode is now EPHEMERAL — scoped to the page you armed it on:
- the zddc-elevate cookie is session-scoped (drops the 30-min Max-Age)
- pagehide clears it, so navigating away / closing drops admin
Because a reload would race the pagehide-clear, every arm/drop path
(toggle, ?admin= URL, banner "Drop admin") now applies IN PLACE and
emits a `zddc:elevationchange` event. browse listens for it and
re-fetches the listing (server-computed verbs) + re-renders the open
preview, so editor affordances reflect the new elevation without a
manual reload.
Validated end-to-end in a containerized Chromium (Playwright over CDP)
against a local zddc-server: the toggle renders for can_elevate, arming
sets the session cookie + armed chrome, "Drop admin" and navigate-away
both clear it, and ?admin=true still arms via the same funnel.
