fix(schedulerclient): parse apiserver OrderMap columnar rows (bug-1491)

Browse source 
The apiserver returns list rows in OrderMap columnar form —
{"Fields":["col",...],"Data":{"col":val,...}} — but the read clients
unmarshalled each row as a flat object, so every field came back empty
(counts were right, values were all zero/"").

Fix: decode rows as apiRow{Fields, Data map[string]json.RawMessage} and
pull named fields out of Data via rowStr/rowInt/rowInt64/rowFloat helpers.
ListNodes, ListQueues, and getJobs (ListJobs/GetJob) all use apiRow now.

TDD: 3 new ordermap_test.go tests built from live-captured apiserver
response shapes (red: fields empty → green: parsed). Live-verified against
t1: node name=t1 cores=8, 4 queues active, 3 jobs with real fields.
