Merge origin/dev (Constellation) into charging-dashboard branch

Reconciles main's line + the charging-dashboard feature with dev's
Constellation work, keeping the Constellation changes. Clean auto-merge
(no textual conflicts); validated post-merge: tsc clean, 34 tests pass
(17 slackbot + 15 charging + 2 constellation).
