dennis zhuang 2933f95672 perf(servers): drop the output sort for Prometheus range queries (#9090)
* perf(servers): drop the output sort for Prometheus range queries

Matrix responses sort samples by timestamp and series by labels while
serializing, so the sort the PromQL planner puts at the root of a range
query plan never reaches the client.

Mark the query as not requiring output ordering in `do_range_query`, and
let the frontend strip the root sort (through projections, and only when
it carries no fetch) before execution. Instant queries are unchanged, so
`sort()` and `sort_desc()` keep their observable order.
