Convert backend to typescript

[amirrr]

There needs to be multiple steps:

Migrate to the newer sequelize-typescript for typescript database models.
Convert every file to typescript and continue in typescript (checkJs: false)
Go through every file and fix typing issues (checkJs: true)

What's the status on this effort? I think we perhaps decided we couldn't do some things because of some fundamental problems, but I forget how we finalized that discussion. Any updates @amirrr

sequilize typescript is still work in progress https://sequelize.org/docs/v6/other-topics/typescript/ and there are some small configurations needed to move to typescript. But there are ways around that and we can do that. I am working on the typescript branch on figuring out the sequilize part but once that's done, we can slowly convert to typescript. I say let's keep this open but mostly focus on getting it to run with typescript complier and then make the change once stable.

This is mostly done, right?

Not yet. It is more like 10% done. This can be considered technical debt we have to address at some point.
