fix: queue-operator dropped reconcile namespace and overflowed hash-range status

main.go called Reconcile(ctx, req.Name) without req.Namespace, so the
Get against the namespaced Queue CRD always 404'd and was silently
swallowed as success -- no shard topics or Redis state were ever created.

Separately, ShardStatus.HashRangeStart/End were uint32, but controller-gen
maps that to OpenAPI format:int32, whose max (2147483647) is smaller than
FullHashRangeEnd (0xFFFFFFFF), so the apiserver rejected every status
update with the (misleadingly empty-looking) "must be of type integer with
format int32" error. Widened to int64, regenerated the CRD, and synced the
chart's bundled copy.
