Subject: [PATCH] [MIRROR] Hidden nodes no longer become visible when copying
 them to another Techweb [MDB IGNORE] (#21775)

* Hidden nodes no longer become visible when copying them to another Techweb (#75969)

## About The Pull Request

Copying techwebs did not take into account whether
available/researched/visible nodes were hidden in the techweb being
copied from, so copying a base techweb to another would reveal all the
bepis tech modules that are available but hidden.
## Why It's Good For The Game

Pretty big cheat. Although you can't print disks any more there are
Technology Disks lying around in science in most stations, so this still
exploitable.
## Changelog
:cl:
fix: copying nodes from a techweb to another no longer reveals hidden
nodes

* Hidden nodes no longer become visible when copying them to another Techweb
