Refresh All Training Data Schedule

Configures the in-process daily scheduler that triggers the composite Refresh All Training Data job — wipe derivative + update primary (over UIP inventory, after waiting on inventory_build) + generate derivative (over the post-update on-disk primary set). Time is interpreted in the project's reference timezone (Eastern). When "Only on trading days" is on, the scheduled tick first asks the NYSE calendar whether today is a trading day and skips the run on closed days. Multithreaded / Max workers / Allow concurrent execution mirror the per-fire parameters from the Refresh All Training Data execution card and are copied onto every scheduled run.
