Require more information when creating organisations

Currently we set not-very-useful defaults for organisation type and
crown status when creating an organisation. This commit adds two field
to the form (in addition to the existing name field) to explicitly ask
for:
- organisation type
- crown status

We need these for all organisations before we can make any of their
services live.

This commit also records any new organisation as not having accepted the
data sharing and financial agreement, because if we don’t know about the
organisation already then they definitely won’t have signed it.
