Fix node-details remove action to preserve confirmation flow

[Copilot]

Removing a node works from the node list but fails from the individual node details screen. The details flow was navigating away immediately on remove, interrupting the confirmation/removal path.

• Root cause

  • NodeMenuAction.Remove in node details invoked onNavigateUp() immediately after dispatching the remove action.

• Code change

  • Updated shared node-details action handling to not navigate up on remove.
  • Remove now follows the same confirmation-first behavior as node list removal.

• Regression coverage

  • Added HandleNodeActionTest in feature:node common tests to verify:
    • remove delegates to NodeManagementActions.requestRemoveNode(...)
    • no immediate navigation occurs

// before
is NodeMenuAction.Remove -> {
    viewModel.handleNodeMenuAction(menuAction)
    onNavigateUp()
}

// after
is NodeMenuAction.Remove -> viewModel.handleNodeMenuAction(menuAction)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
