- PR #104185: fix(cron): keep scheduled jobs running across daemon upgrades

These issues and fixes address a scenario where a stale cached cron.executions module causes import errors (e.g., 'cannot import name ledger_transaction') following execution-module refactors or upgrades. The work focuses on keeping cron stores importable and scheduled jobs running without requiring a daemon restart.
