Create Audit Tables for each entity

[misha130]

As per discussion on the forum: https://forum.codidact.org/t/audit-tables-round-2/548/11
each entity in our database should have an additional table to represent its changes and audit.

May want to use the library of Audit.NET https://github.com/thepirat000/Audit.NET/tree/master/src/Audit.EntityFramework

Should be properly represented in the migration as well.
