lisa.wa: Fix caching of _get_job_df()
FIX
WACollectorBase._get_job_df() should not be cached if the result depends on user input. Disable the cache in those cases.
GitLab Maintenance scheduled for Thursday, 18th December 2025, from 7:00 AM to 10:00 AM BST. GitLab will be in read-only mode and experience short periods of complete downtime (up to 20 minutes) during this window.
