ROOT CAUSE (from instrumented logs):
1. Duplicate entry IDs in LazyVStack — loadMore appended entries
that already existed. IDs 37603/37613 appeared twice, causing
"undefined results" from SwiftUI.
2. Offset drift — marking entries as read shifted the unread filter
results. offset=30 no longer pointed to page 2; entries moved.
3. loadMore returned +0 entries because offset was past the shifted
end of the filtered dataset.
FIXES:
1. Deduplication: loadMore filters out entries whose IDs already
exist in the array before appending.
2. Use entries.count as offset instead of a separate counter.
This naturally accounts for deduplication and status changes.
3. hasMore based on whether new (deduped) entries were actually
added, not just API page size.
Removed all debug logging.
