shared/elevation.js toggles admin mode via the ?admin= URL param, but it's
client-side JS — it only runs on HTML tool pages, where it sets the sticky
zddc-elevate cookie. A raw endpoint (a directory's JSON listing, zip
browsing at /<…>.zip/, the file API) loads no JS, so ?admin=true was inert
there and such requests stayed un-elevated.
ACLMiddleware now reads the same ?admin= toggle directly: true|1|on|yes
elevates the request, false|0|off|no drops it (overriding the cookie for
that request). This is per-request only — the server doesn't set/clear the
cookie; elevation.js still owns sticky persistence on pages. Elevation
grants powers only to a caller who already holds admin authority (every
admin call site re-checks via IsActiveAdmin), so a non-admin's ?admin=true
sets the forensic flag but confers nothing.
Makes e.g. GET /.zddc.zip/?admin=true work for an admin without first
arming the cookie on a page.
