[Master][Bug 648681] Fix Expense Agent KPI report-line drill-down filter

[v-rohangarg20]

Summary

Fixes Bug 648681: the Expense Agent KPI report-line drill-down opened the Expense Report Lines page unfiltered, showing all lines instead of the selected line.

Changes

• EA KPI Entry.OpenCard(): filter the Expense Report Line record on Document No. and Line No. before calling Page.Run, so only the selected line is shown.
• EA KPI Entries page: expose Line No. in the repeater so report-line entries can be distinguished before drilling down.

Testing

• Manually traced the drill-down code path; verified the record passed to Page.Run now carries the expected filters.
