Motivation and Context

This PR adds the following improvements:

• Postgres doesn't add automatically indexes to foreign keys. This PR adds missing indexes for all foreign keys to improve performance. Ref
• Add missing indexes for columns that are queried frequently based on query performance analysis of GCP e.g. audit logs table.
• Upgrade drizzle to latest version. This implied to not pass 0 as limit to the query builder because 0 means no results. Before the upgrade 0 was ignored.
• We were able to get rid of our custom JSON types. Drizzle inserts them now correctly.
