Add warning banner for "insufficient resources"

[marcellamaki]

Overview

In some scenarios, depending on the number of channels/resources available on a device, and the size of a quiz, a coach may not have sufficient resources/questions available to make a quiz of their desired size.

We will add a banner to alert the user in the following scenarios:

• A user does not have enough resources to create their quiz initially (i.e. 18 questions available, but they want a 25 question quiz)
• A user does not have enough resources to add additional sections to their quiz (i.e. the remaining available resources are only 5, and they want to add an additional 25 questions)

If there is a limit in the number of available questions, we should limit the number of questions that a user can add to the number of available resources. For example, in the figma spec below, the validation on the input field should have a max value of 18 (rather than 25, the section max).
