Fix test target compilation (stale status bar init, missing imports)

[datlechin]

The TableProTests target does not compile on main, so the whole test bundle (and CI's test phase) fails. Three test files drifted out of sync with recent feature merges:

• MainStatusBarLayoutTests still calls MainStatusBarView(...) with the old pagination callbacks (onLimitChange/onOffsetChange/onPaginationGo). The Improve pagination UI for query results (page navigation, page size selector) #1364 pagination PRs (feat(datagrid): page-size menu, first/last buttons, and jump-to-page in the pagination bar #1408, refactor(datagrid): de-duplicate pagination helpers and guard All rows on unknown totals (#1364) #1411) changed the initializer to onPageSizeChange/onShowAll/onGoToPage. Updated the call and sorted its imports.
• AWSIAMAuthTests reads .id/.isSecure on a TableProPluginKit type without importing the module (from the AWS IAM work, Support RDS IAM Auth #1291). Added import TableProPluginKit.
• FillColumnTests uses Binding.constant(...) without importing SwiftUI (from Fill Column, Feature Request: Edit Column for all rows in data #1304). Added import SwiftUI.

After these, the test target builds again and MainStatusBarLayoutTests passes. No production code changed.
