Initial commit: Hedena Gold monorepo.

First commit of the Hedena Gold product (separate from gold-bank): branding, package names, and deploy defaults aligned to the new brand; legacy Henza trees stay local-only via .gitignore.

+ * Jest for apps/api.
+ *
+ * `pnpm test` existed in package.json from the start but jest was never a
+ * dependency, so the script always failed. Added during security-hotfix stage 2
+ * with the user's approval, dev-only.
+ *
+ * Unit tests live next to the code as *.spec.ts. The live-server integration
+ * checks stay in scripts/auth-smoke.sh — they need a running API and a seeded
+ * database, which is a different thing from a unit run.
