Blueprint pages should show scan logic

A useful fragment page needs more than a name. It should show the number of scans, the likely route, whether a tool is required, what danger to expect and what the blueprint enables. This helps players decide whether the dive is worth doing now.

Fragment data needs revision dates

Fragment guides can age quickly. Add a checked date to every route and keep a short change log when a patch moves scan locations or changes recipes.
