Upgrading TypeORM

[YazeedLoonat]

What is this feature?
This is a ticket to figuring out a way forward on upgrading our version of TypeORM on the backend. We are currently using a version that is about 1 year old, so we should get some performance/stability gains by upping our version.

Considerations
Since we are pretty far behind, this may require several other packages we use to need to be upgraded as well. This could become a larger task depending on how many/what needs to happen to up all of those

nestjs might need to be upgraded as well depending on if typeorm supports our version

QA NOTES
To be honest every part of the system needs to be tested:
listings
creating, editing, viewing (public and partners)
applications
creating, editing, viewing (public and partners
users
creating, editing, viewing
duplicate listings
resolving, marking as duplicate, viewing
