fix(query-tool): export button hover visibility, jobs tab hide columns and export with txn history

- Increase CSS specificity for .btn-export to prevent portal-shell override on hover
- Remove RESOURCEID and CONTAINERIDS from jobs tab display columns
- Add lot_jobs_with_txn.sql joining JOB with JOBTXNHISTORY for complete export
- Route lot_jobs export through get_lot_jobs_with_history() for full transaction data
