Prevent User Access when configuration incomplete

[NigelPalmer]

Description

There are a number of items of configuration that need to be set up before a user can successfully use the MDE. We should prevent the user from being to log in if any of the following are missing:

1. Core table of star schema is not defined
2. Query builder data types for primitive types are not defined
3. "API Property for APPROVAL_RECIPIENT_KEY email.research.data_specification.recipient is not configured"
4. Once 3 is populated, the email must relate to a user of the system: "Could not find user with email address test@test.com"

Additional context

The core table and query builder data types checks are already carried out when the query builder is accessed. This code should be able to be reused for a login check.
