Live Updates of Devices and Project Deployments

### Epic

_No response_

### Description

**As a:** User

**I want to:** See up-to-date state of projects and devices on the relevant pages

**So that:** I'm able to monitor them reliably

----

Currently, this is handled with polling on various pages of the application, but as the number of users increases, and the amount of data increases requiring pagination and/or increasing transfer size, this starts to become unsustainable.

Server-Sent Events pushing updates to projects and devices would give real-time updates, while completely removing the need for polling, and simplify the client-side logic.

### Which customers would this be available to

All Users, (CE)
