Realign pack sheets into the entities layout and fill the sheet

tools/realign_sheet.py strips the blank spacer rows from a documented
Animals/Monsters sheet, drops the dark-box preview copies and moves the
light frames into the manifest's slot columns, so a sheet pastes into the
template as one block. Both sheets are pasted; the manifest gains the
fifth foal/horse pair the Animals sheet actually has.
