fix: break Koin circular dependency with Lazy<MeshConnectionManager>

MeshConnectionManagerImpl and LockdownCoordinatorImpl constructor-inject
each other, causing a StackOverflowError at Koin resolution time.

The coordinator only needs MeshConnectionManager in two rare paths
(lock-now-ack and post-unlock config reload), so defer its resolution
with Lazy<T> — matching the existing Lazy<MeshRouter> pattern in
FromRadioPacketHandlerImpl.
