Add wikidata to organisation(Account) model

[CloCkWeRX]

It's probably not too common, but if you are dealing with orgs; and they happen to have a wikidata entry; that very quickly uplifts the detail you know.

https://nsi.guide/ gives an indication of how many companies out there are "big enough" to have been added.

Initial implementation would simply be ability to CRUD, and display the wikidata id as a link that opens in a new tab.

If added, potentially other integrations could include:

• One click view a map of the physical branches mapped on OSM
• One click search of open corporates
• import of specific wikidata properties about a company (description, founded date, industry); potentially some tagging automation

Note: if you have an email domain, that can often be automatically resolved to an NSI entry or wikidata ID
