They were made session-only on a misreading: the ask was about the FIRST launch
of a fresh install, not every launch. Restored as they were — restored on
reopen, and travelling with a copied data/ folder.
A first-ever launch already starts with nothing filtered: every selection
defaults to empty or off and there is no code that switches one on. The one
route by which a new installation can come up filtered is a copied data/ folder,
which carries the previous machine's selections by design.
The filtered-out message and the clear-every-filter button stay: they are what
makes a filter that IS set visible, whenever it was set.
