Add materialized view for eCR Version number

[emmastephenson]

What needs to be done

Create a materialized view to store the eCR Version number in our SQL database. This view should contain eICR ID, eCR version number, and maybe set ID.

Why it needs to be done

We need a version ID that will tell us which number a specific eICR is within the set. This could be calculated with:

• The version number already present in the eICR
• The created date of the eCR

Acceptance Criteria

List out all expected functionality/requirements

• There is a materialized view in the database that contains the correct version number for each eICR ID.

There may be a version number included in the eICR already - part of this ticket will be reviewing this field to see if it contains what we need.
