bug-1903: apiserver GetJobsInfo page_token does not advance: the next page repeats the first

Description

Observed: found by the reviewer of task 7.3 (spec job-array-one-based-index) while comparing handler behaviour with HEAD in a unit-test harness: following the page_token returned by GET /xce/v1/jobs (GetJobsInfo) returns the same page again instead of the next one. Reproduced at HEAD (before task 7.3) with a plain filter {submit_user:eq:all} and a small limit, so it is not caused by the element-selection work. Expected: passing the returned page_token yields the next page of rows, and the last page returns no token. Impact: wrong result: clients that page through job listings (xcecli jobs list with paging, REST callers) see the first page repeatedly and never reach later jobs. Found by: review (task 7.3 of spec job-array-one-based-index, 2026-10-01)

Environment

OS: no /etc/os-release; Docker container; NixOS kernel; kernel Linux 6.18.33 x86_64
libc: n/a (pure-Go handler path); host glibc 2.40
Toolchain: gcc (GCC) 15.2.0, meson 1.9.1, Go from the nix dev shell
Build: asan (build.jai); exercised through the non-cgo Go unit-test build of src/frontend/apiserver (the defect is in pure Go)
Code: scheduler-framework @ c30e5f1d (HEAD before task 7.3) and 3457d892
Deployment: none (controllers handler test with an in-memory store); any apiserver with more jobs than the page limit

Reproduction

In a controllers handler test (non-cgo, jobs_handler_test.go fixture), seed more jobs than the page limit.
GET /xce/v1/jobs?filter={submit_user:eq:all}&limit=2; read page_token from the response.
Repeat the request adding &page_token=<token>: the rows are the same as the first page.

Frequency: deterministic (reviewer probe, 2026-10-01)
Evidence: not kept (reviewer's temporary probe test, deleted)

Root cause

TODO: required for fixed/partial
