Pull request overview

This PR reorders conditional checks in the FSM (Finite State Machine) worker to handle validators that aren't in the union or have no realm assignment. The change moves the can_proceed check to execute after the validators union check, allowing the system to process validators union status even when the node lacks a realm assignment or when the network is paused.

Changes:

• Moved the can_proceed check from before the validators union check to after it
• This allows handle_not_part_of_validators_union to be called even when realm_id == 0 or the network is paused
