[old mentor app] rename one-pagers

[joshyellin]

Right now "one pagers" are called "first-day evaluation," but that's a misnomer as we're not doing that on the first day anymore.

I would rename to "One-page evaluation" or "One-pager" or "Evaluation"

Let's go with 1-pager

This is fixed in both apps now.
