Fix 1: Added a <para> to the VitalsController class summary citing
docs/research/2026-06-15-layoutdesc-format.md §11 as the source of the
three dat element ids, giving a paper trail back to the evidence per
the project's cite-in-comments rule.
Fix 2: Changed FakeLayout in VitalsBindingTests to accept (uint id,
UiElement e) tuples instead of (string idHex, UiElement e), and updated
all three call sites to pass VitalsController.Health/.Stamina/.Mana.
Tests now follow the constants automatically if they ever change rather
than silently passing with stale hex literals.
