Reduce Repo Code with DBOS Migration

Identify an opportunity to massively reduce the amount of code (lines of code) in any part of the repo: - Similar functionality that can be unified and reused - Code that has been valuable but no more - Front end component or group of them duplicates another component functionality. Use the most modern and nice looking - Move to DBOS and get rid of supporting functionality relying on DBOS - etc. Implement it

Unified duplicate code in the API crons, jaahd helpers and web dialogs/log views/states: net −213 LOC. Full gate green; PR #5333 merged; Jaah Deploy succeeded. Bigger rollout-gated cuts and UI suggestions listed in the report (task filing refused, 403).
