Call sync_from_system before_sync_workers at startup

[agrare]

#23112 allowed non-rails workers to be marked as started even if they didn't go through run_single_worker with database access, specifically the opentofu-worker.

The issue here is that the threads which keep the list of current deployments and pods up to date are not started by MiqServer#start_workers, rather only the initial startup has completed and MiqServer has moved to the MiqServer#monitor_workers loop. The result of this was everything worked if the server was started with the embedded_terraform role disabled and the role was enabled later, but if the role was enabled at startup the wait_for_started_workers would never complete and timeout.

Fixes ManageIQ/manageiq-providers-embedded_terraform#81

WIP pending a live test to confirm the fix.
Also want to see if there is any reason to not just call sync_from_system at the start of sync_workers instead of having that requirement of every caller.
