fix: release lease on unused timeout when hooks are configured

When a lease times out without any client connection and hooks are
configured, _cleanup_after_lease skipped the afterLease hook (correct)
but also skipped calling _request_lease_release (bug). This left the
exporter permanently stuck in LeaseReady status because the controller
was never notified that the lease should be freed.

Add _request_lease_release() call in the else branch of
_cleanup_after_lease so the controller always frees the lease,
regardless of whether the afterLease hook ran.

Fixes: #237
