(OPCUA) Enabled Security mode shall update Node-Tree-Explorer to show added nodes in ServerCapabilities and ServerConfiguration

As a Product Owner, I want the Node-Tree-Explorer to correctly display newly added nodes when security mode Basic256Sha256 is enabled, so that users see the enabled OPC UA Push Management in the updated ServerCapabilities and ServerConfiguration structure accurately.

Acceptance Criterias:

• When security option Basic256Sha256 is enabled, the OPC UA Push Management is visible to users.
• The Object ServerCapabilities below the Server node is displayed as "added" in the Node-Tree-Explorer.
• Verify and ensure nodes from the namespace files Base_CertMan_* are displayed correctly:
  • Nodes related to ServerConfiguration are visible under Server -> ServerConfiguration.
  • Nodes related to ServerCapabilitiesType are visible under ObjectTypes -> ServerCapabilitiesType.
• The Node-Tree-Explorer updates dynamically to reflect the changes without requiring manual refresh or reload.
• Display consistency must be ensured for all affected nodes across the updated security context.
