feat: skip simulation when enforced simulations container is active

[matthewwalsh0]

Explanation

When a transaction has the EnforcedSimulations container type, the simulation is redundant since the enforced simulation flow handles balance change protection separately. This PR skips the standard simulation in that case to avoid unnecessary network calls and potential conflicts.

Changes

• Skip balance change simulation when containerTypes includes EnforcedSimulations
• Re-check containerTypes in the update callback to handle the race condition where simulation starts before the container type is set
• Use fresh state from skipSimulationTransactionIds in the callback instead of a stale closure, fixing an issue where toggling enforced simulations off would not restore balance changes

Note

Medium Risk
Changes when/if simulationData is produced and persisted during transaction updates, which could affect balance-change protection behavior and downstream consumers that expect simulation results. Scope is contained and covered by a new unit test, but it touches core transaction lifecycle logic.

Overview
Transactions marked with containerTypes: [EnforcedSimulations] now skip balance-change simulation (and avoid getBalanceChanges calls) when editable params change and would otherwise trigger re-simulation.

The simulation update path now re-checks the latest containerTypes/skip state inside the state update callback via a new #isBalanceChangesSkipped helper to avoid race conditions and prevent persisting simulationData when simulation is meant to be bypassed. Changelog updated and a regression test added to assert simulation is not re-run in this mode.
