Merge remote-tracking branch 'origin/main' into feat/331-collections-pr2

#332 PR 3 (#428) hands a Tags & categories Browse to the next Images mount;
this branch mounts Images as a collection page too. Both imports are kept; a
collection page neither restores the last visit nor takes the Browse hand-off
(it is not the Images page), and the Images page keeps both the handed
category and the collection filter.
