Make cluster dashboard certificates list ns filter agnostic

[richard-cox]

Summary

Related to #10025 / #10024

Occurred changes and/or fixed issues

• The cluster dashboard page contains tabs
• Tabs contain lists
• One tab shows lists of events (non-namespaced resource), the other certificates (namespaced resource)
• By default lists will filter rows of namespaced resources by the namespaces selected in the header filter
• This works fine for root lists, and is ignored for lists with in the detail page of resources (as they're showing resources associated with the primary resource)
• For lists that are in overview pages though we don't have a pattern
• For this context and use case it feels discombobulating to filter by namespace
  • navigating to the local cluster and viewing cert list will by default not show any due to the user only namespaces filter

Areas or cases that should be tested

• cluster dashboard --> certificates tab
• entries do not change given the value of the ns filter
