fix: request enough rows for popup dictionary values - #9875

Problem

Popup dictionary values beyond the default page size of 10 cannot be fully converted or displayed.

Change

Pass a pageSize based on the number of selected values, while keeping 10 as the minimum page size.

Validation

• git diff --check
• Manually verify that popup dictionary requests include enough rows for more than 10 selected values.

Full Vite/Jest validation is currently blocked by the existing local dependency environment.
