Fix F3 Node startup #1543
Description
On first boot with F3 enabled, node startup fails with F3 is enabled in config but initial F3 state is missing in committed state, even when F3 state is present in genesis. This happens because startup checks query committed state before InitChain has committed genesis, so F3 initialization should be deferred until committed state becomes queryable, while preserving fail-fast behavior for real config/state mismatches.
