fix: Could not verify JWT bug

[DafyddLlyr]

What's the problem?

• API errors thrown when hitting certain routes called via the frontend (e.g. /diff)
• Errors suggest an issue with validation - Could not verify JWT
• Likely caused by recent change to permissions (chore: Drop adminClient (1/2) #2356 & feat: Drop adminClient (2/2) #2375)

What's the cause?

• The middlewares useRoleAuth and useLoginAuth were only getting JWT's from req.cookies
• However, auth headers were being used by the frontend to pass along the JWT to the API

What's the solution?

• Update middlewares to get this data from the auth headers

Why wasn't this caught in testing?

• API docs were reading req.cookies despite the additional Swagger authorisation
• E2E tests are adding a cookie to all requests using the helper method createAuthenticatedSession()
