Switching tab or folder while a type filter was active left the
filter applied silently — the chip cloud regenerated from the new
result set so no chip lit up, but the documentType= query param
kept narrowing the list. Reset typeFilter to undefined whenever tab
or selected folder changes.
Also use TYPE_LABELS for chip text so the filter chips match the
human-readable labels already shown in the row's Type column.
