[chore] local instance count query caching, improved status context endpoint logging, don't log ErrHideStatus when timelining (#3330)

Browse source 
* ensure that errors checking status visibility / converting aren't dropped

* add some more context to error messages

* include calling function name in log entries

* don't error on timelining hidden status

* further code to ignore statusfilter.ErrHideStatus type errors

* remove unused error type

* add local instance status / domain / user counts

* add checks for localhost

* rename from InstanceCounts to LocalInstance

* improved code comment
