Added auto-add seats modals to scheduled edit view

This needs some refactoring but basically splitting the request seat
modal into a request seat and add seat mode. This was a request from
the J4 schedulers but also will be handy for FTD schedulers as you it
doesn’t really make sense to request seats from yourself.  This saves
FTDs that will not have their MTFs using FTSS right away be allowing
them to still use the system without having to learn extra views or do
redundant steps.
Minor visual tweaks to TTMS view
Removed extra padding on the .wrapped div
