Layout fixes in preparation for expansion

I'm working on the expansion boxes and pages as i've said in my other devlog, but first i wanted to revisit the foundation to check if everything wa alrhigt before adding to it, aand...i found things to change. 

• removed the gap between the bottom folded half page and the left inside page
• adjusted the overall layout and alignment of the pages
• fixed some leftovers drawings mistakes

the gap was there because i thought it might've accounted for an increase in thickness in case someone would overstuff the booklet with other sheets or cards, or even just for heavy alignment issues, but the more i looked at it, and tried it again, the more it seemed like a useless fix, and so i aligned it again the the upper page. 

i found out also the the inside and outside pages were not as equally spaced out as i thought they were; i'm still unsure on this, but i'm confindent i should have improved the alignment chances during printing.
