Fix report list not reloading when switching filter

[zhaoyulin1828]

Problem

For admin users, when there are no "Not Dealt" reports, switching to "Dealt" could show an empty list and fail to load handled reports.

Root Cause

ReportModel.filterOption only cleared reports, but the list loading flow in AsyncCollection was not reliably retriggered in the empty-to-empty transition.

Fix

• Reset endReached when filterOption changes.
• Rebuild AsyncCollection on filter change via .id(model.filterOption) in ReportPage.

Verification

• Open Reports Management as an admin account.
• Ensure "Not Dealt" is empty.
• Switch to "Dealt" and "All Reports".
• Lists now load correctly instead of staying empty.
