fix: plumb ctx into session db methods

[mistahj67]

Description

Plumb context into gorm session db methods
https://gorm.io/docs/context.html#Context-Timeout

Motivation and Context

Currently as it stands any endpoints that rely on purely gorm do not respect request.Context and as such timeouts are not respected either. While we want to eventually get to the removal of the gorm dependency altogether, that is a long way and a lot of effort away and this I think this approach would give us that much room to maneuver while we get there.

How Has This Been Tested?

Using a rest client and the prefer header
Add a sleep inside of the handler
Look for the 500 request timed out after exceeding the timeout. (Note: the request will take as long as the sleep is set, it's not tied to the prefer header)
