Process HQ grid export — increase row limit beyond 10,000 rows

Process HQ's grid reports currently cap Excel exports at 10,000 rows and 50 columns. For enterprise use cases involving clinical trial data, financial reconciliation, or large operational datasets (e.g., 1M+ records), this is severely limiting.
We need either a configurable export limit per environment, a background/async export smart service trigger from within Process HQ, or a CSV export option without the row cap.
Impact: teams are forced to build parallel export workflows outside Process HQ, defeating its purpose as a self-service analytics tool.
