UX: Refresh buttons in spaces/data panes are confusing

[nsheaps]

Description

The refresh buttons appear in both the Spaces pane and Data pane, which is confusing. The refresh action should only exist on the Data page, and should show the update process inline rather than closing the pane.

Proposed Changes

1. Remove refresh buttons from the Spaces pane
2. Keep refresh buttons on the Data page only
3. Show the update/refresh process inline in the pane rather than closing the pane when clicked

Current Behavior

Refresh buttons in both panes; clicking them closes the pane, making it hard to see what happened.

Expected Behavior

Refresh only on Data page, with inline progress indication.
