Implement the sole HTTP invoke path (ADR-042/047) in
src/server/gateway_routes.rs: POST /call reads { operation, input },
resolves identity via the shared ResolvedIdentity extractor, dispatches
via GatewayDispatch::invoke, and returns ResponseEnvelope as JSON with
errors mapped via call_error_to_http_response. GET /search dispatches
services/list (AccessControl-filtered); GET /schema dispatches
services/schema with an ACL pre-check (unauthorized -> 403). POST /batch
loops over invoke returning an array; POST /subscribe projects the
response as SSE (text/event-stream) with data frames for call.responded
and an error event for call.aborted. Internal ops return 404. Wire the
real handlers into adapter.rs router, replacing the placeholder 501s.
