edit mobile lend button area

This would replace the previous lend button version with a simple lend button that goes across the width of the screen and sticks to the bottom, similar to the Airbnb app.  When clicked, the button would open the lend form with the funding progress bar, loan amount and interest fields as seen in the desktop version, in the full screen of the mobile device, and from there the user could go through a similar lend form process flow as with large devices.

The big follow button would not display stuck to the bottom, but the mobile version instead displays a follow option within the profile.
