Prepare the 1.2.1 release

`discourse/truth-helpers` no longer exports `isEmpty` (the truth helpers
moved to `@ember/helper`), so the import resolved to `undefined` and the
template threw "can't convert undefined to object" as soon as a report
rendered. Take `isEmpty` from `@ember/utils` instead, which is present on
both 2026.10 and 2026.11.

+## 1.2.1 — 2026-11-05
+
+Restores the dashboard on Discourse 2026.11. Discourse removed `isEmpty` from
+`discourse/truth-helpers` when the truth helpers moved to `@ember/helper`. The
+dashboard imported it from there, so the value resolved to `undefined` and the
+template threw `can't convert undefined to object` as soon as a report
+rendered, leaving every tab blank. The helper is now imported from
+`@ember/utils`, which exists on both 2026.10 and 2026.11.

 ## 1.2.0 — 2026-09-27
