Sun Catering v17.5.17

- In the client-offer inline editor, the "Everything under control" block now has a multiline editor for all list items.
- The block title and each control line are saved per proposal and immediately rebuild the same preview/PDF pages.
- Two table photos are now available through a guaranteed embedded fallback, so they do not disappear because of local file/fetch problems.
- Table photos are automatic: 0 photos when there is no free space, 1 photo for a smaller gap, 2 photos for a larger gap. They never create a new page.
- The old optional "final gallery" switch is no longer used; the whitespace-fill rule controls visibility.
