feat(web/panettone): Log when users change issue statuses
Log in the database, in a way that will generalize to tracking edit history as well, when users change the status of an issue. To facilitate easily knowing who is currently authenticated (without introducing a circular dependency) the authentication-relaated code has also been factored out into its own package, which is nice because we want to replace that sooner rather than later anyway. Fixes: #13 Change-Id: I65a544fab660ed1c295ee8f6b293e0d4945a8203 Reviewed-on: https://cl.tvl.fyi/c/depot/+/1496 Tested-by: BuildkiteCI Reviewed-by: tazjin <mail@tazj.in>
