Drop the bottom-right floating "Admin mode" switch in favour of a proper
account menu in the header's upper-right (every tool's .header-right).
New shared/profile-menu.{js,css}: a circular avatar button (email initial)
opening a dropdown with the signed-in email, an "Admin mode" item (only for
can_elevate principals — drives elevation.setOn/setOff, drops on leave),
Profile (/.profile), and Access tokens (/.tokens). The panel is portaled to
<body> + position:fixed so it overlays content reliably regardless of the
app's stacking contexts; the button shows a red ring while elevated.
No logout: authentication is the upstream proxy's concern (oauth2-proxy /
Authelia) — ZDDC owns no session, so the menu doesn't render sign-out.
elevation.js keeps the state machine (cookie, armed banner/frame, ephemeral
pagehide-clear, zddc:elevationchange, ?admin= URL) but no longer renders any
control — the profile menu is the UI. elevation.css drops the floating-
toggle styles (keeps banner + frame). All 7 templates drop the dead
elevation-toggle placeholder; all 7 build.sh bundle profile-menu.{js,css}.
Validated in a containerized browser: menu items, links, elevation arming +
armed ring, dropdown overlays content, no floating toggle.
