### What happened

On the Spark Application list, editing an application from page 2 or later and returning to the list resets the table to page 1.

The edit action stores the current page in session storage under `sparkAppPageNo`, while the Spark application list restores it from `appPageNo`. Because the keys do not match, the saved page is never restored.

Steps to reproduce:
1. Open the Spark Application list with enough applications for multiple pages.
2. Navigate to page 2 or later.
3. Click Edit on an application.
4. Return to the Spark Application list after editing.

Expected: the list returns to the previously selected page.
Actual: the list returns to page 1.

The equivalent Flink application flow consistently uses `appPageNo`.

Search the Spark application list and edit flow for `sparkAppPageNo` and `appPageNo`, then compare the equivalent Flink application flow. Reproduce the issue from page 2 or later, align the session-storage key with the list's restored key, and verify that returning from editing preserves the selected page.
