New web-svc-mirror role: an nginx vhost that proxies and caches exactly
the external asset hosts aggregated from all deployed applications' CSP
whitelists (external_asset_origins filter) under first-party paths
(/<origin-host>/...), refusing every other upstream. svc-net-tor
consumes the service, so any tor deployment automatically serves the
mirror on its onion.
For apps with services.tor.enabled the shared body filter rewrites
external asset URLs in HTML to the onion mirror (onion sessions only;
clearnet untouched) and the CSP builder allows the mirror origin in the
asset directives. The dashboard's keycloak-js vendoring is reverted:
onion sessions now load the adapter through the mirror, clearnet loads
jsdelivr directly as before.
Verified: variant=0 deploy green (failed=0), dashboard 14/14 over onion
with keycloak-js served through the mirror, mirror spec green, health
check accepts the 404 vhost root.
