Footer does not smart-wrap when it is too large for the screen

---@0.0.8
golang `lipgloss` has bindings for wrapping text to a max size. Additionally, we may want to look at more intelligently handling keyhelps. Is it worth it to investigate the bubbles keyhelp widget?

Implemented some simple wrapping logic in the Model footer function. Further logic required in widget specific keyhelps to further wrap effectively.
