Loki runs SingleBinary with auth disabled and answers GET on
/ingester/shutdown and /flush, so an RBAC `get` on services/proxy for
loki:3100 would not be read-only. Put an nginx allow-list in front of it
(query, query_range, labels, label/<name>/values, series; GET only;
upstream URI rebuilt per location) and grant the paperclip read SA
`get` on that Service only. Owner decision: REN-622 (option A2).
