Move the iTelescope network reference and campaign under itelescope/

Preparing to merge this repository into a combined astrophotography
repo. The network review, the southern-target guide, the drain campaign
and the observing plans all belong together under one directory; the
Default Workflow files (CLAUDE.md, docs/, state/) stay at the top level
because they will govern the combined repository rather than just this
part of it.
