Fix: pbs pro qstat bug

[imdxz]

• Fix pbs job id in qstat: <JOB_ID>.<PBS-server> instead of <JOB_ID>.opbs
• Use qstat -x for querying present and history jobs (qstat -H --hday 7 gives error)

Thank you for your PR.

In my environment, qstat is a wrapper command, and the -H --hday 7 option appears to be specific to that wrapper.

Unfortunately, I don't have access to the non-wrapper version of qstat, so I’m unable to test the -x option you suggested. However, based on the PBS manual, it seems that the option should work as expected:

Thanks for merging!
I'm testing on NSCC Singapore's PBS Pro system where qstat -H --hday 7 isn't available. The qstat -x approach works well for us and should be more portable across PBS installations.
