Say what a database or log target's attempt did, without a status (closes #388)

In the event log and on an event's page, every attempt by a `database` or `log` target read "success  Status: — (no response)". Those targets make no HTTP request, so there is no response to have, and "no response" reads like a failed connection, which is what it means for an `http` target. A successful `database` attempt now reads "archived" and a successful `log` attempt "written to the log", with no status shown; a failed one keeps "failure" and its error line, also with no status. `http` and `slack` attempts are unchanged. The change is in the one shared attempt template.
