fix(apiserver): job_status notnull filter matches every job (bug-1504)

`xcecli jobs list -a` returned "no job found" even when jobs existed.
FilterRows routes every condition on a bitmask field (job_status /
host_status) to MatchesBitmaskCondition, which only implemented OpEQ/OpNE
bitmask semantics — the `-a` filter compiles to `job_status notnull`
(OpNOTNULL), which fell through to `return false` and filtered out every
job. (The default list's `notin(EXIT,DONE)` is compiled to OpEQ(mask), so
it was unaffected.)

Add OpISNULL/OpNOTNULL branches to MatchesBitmaskCondition that test the
raw field value. New query_test.go: 3 regression tests (notnull matches
all, null matches none, bitmask notin path unaffected), RED->GREEN.
Verified live: `xcecli jobs list -a` now lists all jobs including DONE.
