Oded Viner 13faad2269 osd: validate node topology to prevent invalid crush map hierarchy

add a validation check to fail osd deployment when topology labels
like rack or chassis are duplicated across parent domains
(e.g., zones). this prevents invalid crush map hierarchies
(dfbugs-2610).

Breaking Changes

Rook now validates node topology during CephCluster creation to prevent misconfigured CRUSH hierarchies. If child labels like topology.rook.io/rack are duplicated across zones, cluster creation will fail. The check applies only to new clusters without OSDs; existing clusters will log a warning and continue. To bypass, set ROOK_SKIP_OSD_TOPOLOGY_CHECK=true in the operator configmap. See #16017 for details.

Features

Previously, only the latest version of helm was tested and the docs stated only version 3.x of helm as a prerequisite. Now rook supports the six most recent minor versions of helm along with their their patch updates. Explicitly, helm versions 3.13 and newer are supported.
Add support for specifying the clusterID in the CephBlockPoolRadosNamespace and the CephFilesystemSubVolumeGroup CR.
