test(handlers): add org_scope coverage — orgRootID + sameOrg at 0% (#1953)

Adds 10 sqlmock-backed tests covering the cross-tenant isolation
helpers introduced in #1953.

Covered:
- orgRootID: happy path (child→root), workspace-is-root, no rows,
  DB error, empty root string
- sameOrg: identical IDs (short-circuit), same org root,
  different org roots, orgRootID fails, orgRootID not found

Closes #1953 follow-up (test debt)
