BREAKING: Remove Partitioned Stream Positions (#2096)
* go mod tidy

* Break complement to check it fails CI

* Remove partitioned stream positions

This was used by the device list stream position. The device list position
now corresponds to the `Offset`, and the partition is always 0, in prep
for removing reliance on Kafka topics for device list changes.

* Linting

* Migrate old style tokens to new style because element-web doesn't soft-logoout on 4xx errors on /sync
