Add fuse-backed org search to superadmin org list (#2277)

Closes #2276 

Adds a simple search bar to the superadmin interface that allows users
to search for orgs by org name, id, users (names and emails), and
subscriptions (subscription id and plan id).

[Extended search](https://www.fusejs.io/examples.html#extended-search)
is enabled, so exact search terms like `=stripe:sub_xxxxxxx` can be used
to find a specific org directly. [See the
docs](https://www.fusejs.io/examples.html#extended-search) for what
operators are available.
