ui: sql activity pages depend on node info

[matthewtodd]

Fixes #85249.

Previously, the statements, transactions, and transaction details pages had an implicit dependency on the state.adminUI.nodes list in the redux store, and without that list, the Regions/Nodes columns and filters would be incorrectly hidden for multiregion clusters, unless the user happened to have already browsed through a page (such as statement details) that loaded the list.

(This bug was affecting dedicated cloud clusters only. Self-hosted clusters were working properly because their global mechanism to sync alert data happened to refresh the node list.)

This change makes the dependency explicit and refreshes the list of nodes on entering those three pages.

Before	After

Release note (bug fix): The statements, transactions, and transaction details pages in the admin console now properly show the Regions/Nodes columns and filters for multiregion clusters.

Encountered an error creating backports. Some common things that can go wrong:

1. The backport branch might have already existed.
2. There was a merge conflict.
3. The backport branch contained merge commits.

You might need to create your backport manually using the backport tool.

@matthewtodd looks like the backport to 22.1 didn't happen, can you create one? Thanks!
