Create "Add Org" Page that Admin will use to Add new Org to DB (Routes)

[klinkoberstar]

This PR will create the page for the Admin to use to add a new org to the DB. The routes for this page are created in #206

Some specifications for this page:

• Admin email enter twice to confirm.
• Admin will have to enter name, phone, status (the non nullable columns in the org table.
• By default status should be set to invisible.

This page will be accessed from the Admin home page created in #204 and #204

Once Org is created, this will trigger:

• An email to be sent to the org to set up their profile (This is covered by #48)
• Adding the org to the database (should be completed as part of this issue!)
