Summary

Contributes to #9545

Occurred changes and/or fixed issues

• Update feature flag text given change to vai feature flag name
• Ensure cluster explorer More Resources Role and Cluster Role tables use server-side pagination
  • default headers were provided, which meant the ui thought there were overrides and used them instead
  • as the default headers are the same as if they weren't hardcoded removing them is fine
• Moved Global Settings --> Performance pagination setting to top of page
• In some scenarios duplicate filter query params were being sent. Added a check deep down in pagination code to ensure dupes aren't sent
• Fixed an issue which meant the age column did not appear as the last one
