CONSOLE-5398: Remove events card from node overview dashboard

[jeff-phillips-18]

Closes CONSOLE-5398

Note
This feature is available in Tech Preview only.

Analysis / Root cause:
The Node overview dashboard needed to remove the Events/Activity card to streamline the UI when the FLAG_NODE_MGMT_V1 feature flag is enabled.

Solution description:

• Added conditional rendering in NodeDashboard to hide the Activity card when FLAG_NODE_MGMT_V1 is enabled
• Enhanced DashboardGrid to support optional left and right card columns with dynamic main grid span calculation
• Added comprehensive RTL tests for DashboardGrid (7 tests) and NodeDashboard (5 tests)
• Enhanced InventoryCard tests with feature flag path validation
• Updated InventoryCard to use correct pod navigation path based on feature flag (workload tab path vs legacy path)
• Fixed import path for NodeGroupEditButton in NodesPage to avoid barrel imports

Screenshots / screen recording:

*** With tech-preview ***

*** Without tech-preview ***

Test setup:

1. Ensure you have a cluster in tech preview mode with the FLAG_NODE_MGMT_V1 feature flag available
2. Navigate to Compute → Nodes → Select a node → Overview tab

Test cases:

• When FLAG_NODE_MGMT_V1 is enabled, verify Activity card is not visible in the Overview dashboard
• Verify main cards expand to full width when Activity card is hidden
• Verify Details and Inventory cards remain visible regardless of flag state
• Click on Pods in Inventory card and verify navigation goes to /k8s/cluster/nodes/{name}/workload/pods when flag is enabled
• When FLAG_NODE_MGMT_V1 is disabled, verify Activity card appears in the right column (legacy behavior)
• Verify pod navigation uses legacy path /k8s/cluster/nodes/{name}/pods when flag is disabled
• Verify DashboardGrid adapts layout correctly when cards are conditionally hidden

Browser conformance:

• Chrome
• Firefox
• Safari (or Epiphany on Linux)

Additional info:
This change maintains backward compatibility by conditionally showing the Activity card based on the feature flag state. The DashboardGrid component now intelligently adapts its layout to provide optimal space utilization when side columns are absent.
