fix: re-enable leader check in API router and fix stepdown simulation

Browse Source 
Re-enabled the leader check in JetStreamApiRouter.Route() that was
commented out during B8 agent work. Added BecomeLeader() method to
JetStreamMetaGroup for single-process test fixtures to simulate
winning the post-stepdown election. MetaControllerFixture now
auto-calls BecomeLeader() after a successful meta leader stepdown.
