Cluster diagram: migrate Edge to Add-DiaNodeEdge + add per-broadcast-domain Data Network detail

[Copilot]

Two enhancements to the ONTAP cluster diagram:

Edge cmdlet migration

Replaces all raw Edge -From … @{…} PSGraph calls across four diagram files with the Add-DiaNodeEdge wrapper introduced in Diagrammer.Core 0.2.39. Module minimum version bumped accordingly.

Old	New
color / style / penwidth (int)	-EdgeColor / -EdgeStyle / -EdgeThickness
penwidth (float) / style='filled'	-GraphvizAttributes @{penwidth=1.5} / @{style='filled'}
label / fontcolor / fontsize	-EdgeLabel / -EdgeLabelFontColor / -EdgeLabelFontSize
minlen / tailport / headport	-EdgeLength / -TailPort / -HeadPort

Float penwidth and style='filled' pass through -GraphvizAttributes since they fall outside EdgeThickness [int] and the EdgeStyle ValidateSet respectively.

Per-broadcast-domain Data Network detail

The cluster diagram previously showed a single generic Data Network switch with no topology context. Now, each non-Cluster broadcast domain is rendered as its own subgraph node below the switch, listing its port members.

# For each non-Cluster broadcast domain fetched via Get-NcNetPortBroadcastDomain:
Add-DiaHtmlSubGraph -Name "${BDomainSafeName}BroadcastDomain" `
    -TableArray $PortTextItems `   # one Add-DiaNodeText per node:port member
    -Label "$($BDomain.BroadcastDomain) | IPSpace: $($BDomain.Ipspace) | MTU: $($BDomain.Mtu)" `
    -LabelPos 'top' -TableBorderColor '#70AD47' -NodeObject …

Add-DiaNodeEdge -From 'DataNetwork' -To "${BDomainSafeName}BroadcastDomain" `
    -EdgeColor '#70AD47' -EdgeStyle 'dashed' -Arrowhead 'none' -Arrowtail 'none' …

Domains with no ports render a "No Ports Assigned" placeholder. The section is isolated in its own try/catch so failures don't affect the rest of the diagram.

Pull request overview

This PR enhances the ONTAP diagram generation by migrating edge rendering to the Add-DiaNodeEdge wrapper (Diagrammer.Core 0.2.39+) and expanding the cluster diagram’s “Data Network” section to include per-broadcast-domain topology details.

Changes:

• Replaced multiple raw PSGraph Edge calls with Add-DiaNodeEdge across several diagram scripts.
• Enhanced cluster diagram to render each non-Cluster broadcast domain as its own subgraph with member ports.
• Bumped the required Diagrammer.Core minimum version to 0.2.39.

• Get-NcNetInterface -Controller $Array is called twice per node (for node_mgmt and intercluster), which can be expensive on large clusters and increases API load. Fetch interfaces once outside the node loop (e.g., cache the result in a variable) and then filter that cached collection per node/role.

                            $ClusterHa = try { Get-NcClusterHa -Node $Node.Node -Controller $Array } catch { Write-PScriboMessage -IsWarning $_.Exception.Message }

                            $NodeMgmtAddress = Get-NcNetInterface -Controller $Array | Where-Object { $_.Role -eq 'node_mgmt' -and $_.HomeNode -eq $Node.Node } | Select-Object -ExpandProperty Address
                            $NodeInterClusterAddress = Get-NcNetInterface -Controller $Array | Where-Object { $_.Role -eq 'intercluster' -and $_.HomeNode -eq $Node.Node } | Select-Object -ExpandProperty Address

• The PR description says each broadcast-domain label should include IPSpace (e.g., BroadcastDomain | IPSpace: ... | MTU: ...), but the label currently only includes MTU. Either update the label to include $BDomain.Ipspace or adjust the PR description so they match.

                                        -TableBorder 1 `
                                        -Label "$($BDomain.BroadcastDomain) | MTU: $($BDomain.Mtu)" `
                                        -LabelPos 'top' `

• Edge-cmdlet migration looks incomplete in this file: there is still a raw Edge call in the Aggregates section (Edge -To "$($VserverNodeName)Aggrs" -From $VserverNodeName ...). If the intent is to replace all PSGraph Edge usages with Add-DiaNodeEdge (as stated in the PR description), migrate the remaining call(s) as well to avoid mixed APIs and keep the Diagrammer.Core minimum-version bump justified.

                        if ($VolSubGraphObj) {
                            Node "$($VserverNodeName)Vols" @{Label = $VolSubGraphObj; shape = 'plain'; fillColor = 'transparent'; fontsize = 14 }
                            Add-DiaNodeEdge -From $VserverNodeName -To "$($VserverNodeName)Vols" -EdgeColor $Edgecolor -Arrowhead 'box' -Arrowtail 'box' -EdgeLength 2 -GraphvizAttributes @{style = 'filled'}
                        }

$Port.NodeName is referenced when naming/connecting the per-node ClusterPorts subgraph and edges, but $Port comes from the prior foreach ($Port in ...) loop. If a node has zero cluster ports, $Port will be $null or a stale value from a previous node, causing incorrect node names/edges (or runtime errors). Use $Node.NodeName (or an explicitly constructed per-node name variable) instead of relying on $Port outside its loop, and only create the subgraph/edges when there are cluster ports for that node.
