fix: use msiextract for tkinter, fix step numbering, graceful Docker fallback

- Replace 7z with msiextract (msitools) to extract tkinter from
  python.org's individual MSI packages (tcltk.msi + lib.msi)
- Fix build step numbering to /9
- Docker job continues on login failure (registry may not be enabled)
- Show makensis output for debugging
