Proposed change

Speed up listing issues via the repairs websocket api

I was testing shelly issues and had created 200 issues and I noticed this was a bit slow converting to dict. It looks like python/cpython#114087 will make it a bit faster eventually, but since we use a dict comp pattern for all the other registries, the simplest change was to use it here as well
