docs: add Stackbit 1248 vertical layout screenshots and documentation
What changed, and why it matters
This commit only adds documentation screenshots and text describing a vertical layout for the Stackbit 1248 metal backup format. It also updates a simulator script used to capture those screenshots. There is no code change that affects security.
No security action needed; this is a documentation-only change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff is limited to documentation Markdown, two binary PNG images, and a simulator input sequence file. No firmware, cryptographic, or UI logic code is modified. The changes describe an existing vertical Stackbit layout and add simulator button presses to generate corresponding screenshots.

This metal backup format represents the BIP39 mnemonic word's numbers (1-2048). Each of the four digits is converted to a sum of 1, 2, 4 or 8. This option does not print even if a printer driver is set.
