Adds a second mode to the organize-imports dialog: instead of creating
one new page per approved group (which could produce dozens of tiny
pages), the user can pick an existing destination page and have every
approved item moved into it. No catalog page is created in this mode.
- organizeImportFurni: groups accept destinationPageId; when set, the
existing page is reused, new offers append after its current highest
order, moved offers keep their original name, and the real page
caption is used for logging and results
- OrganizeImportsDialog: mode toggle (create pages / move into page),
searchable destination picker via /api/admin/catalog/tree?search=,
name/icon/layout editors hidden in move mode, button shows a move
count, and the success toast reports moved/added instead of pages
- en + nl translations for the new mode, destination, and move keys
