Add report.bat to collect diagnostics, and a VERSION.txt stamp

Nothing in this repo ever updated Melissa's PC, so "it isn't working"
could not be told apart from "she is running last month's copy" - which
is what it turned out to be today.

report.bat writes one text file to the Desktop with the installed
version, which files are present, whether WinSCPnet.dll loads or is
blocked, every entity.json (passwords masked to ********), what is
actually sitting in today's date folders, and the tail of the last log.

A missing VERSION.txt is itself the answer: it means the copy predates
2026-08-26 and has no setup wizard.
