Description
etcd 3.6 STILL serves /v3/kv/lease/{revoke,timetolive,leases} via additional_bindings (gw/rpc.pb.gw.go:1435,1482,1522).

Our generated descriptors preserve the bindings (rpc_pb.lua:9732,9751,9759) — the data is there — but http_path_from_options (app/etcd/pb/routes.lua:103-108) returns only h.post and DROPS additional_bindings, so those paths fall through to 'path not found' (json.lua:632).

The prefix half matches upstream exactly (only /v3, no /v3alpha//v3beta). Fix is contained: make http_path_from_options return a list including additional_bindings and have the route table register each.
Acceptance criteria
/v3/kv/lease/revoke, /timetolive, /leases all serve identically to their /v3/lease/* equivalents; a test hits the deprecated paths.
