Fix remaining typescript issues, enable `tsc` (#32840)

Fixes 79 typescript errors. Discovered at least two bugs in
`notifications.ts`, and I'm pretty sure this feature was at least
partially broken and may still be, I don't really know how to test it.

After this, only like ~10 typescript errors remain in the codebase but
those are harder to solve.
