/**
 * Shared state shape + API bodies for the Organization pages
 * (`/create/organization`, `/edit/organization-:id`, `/duplicate/organization-:id`).
 *
 * One flat form holds AD_Org + AD_OrgInfo (letterhead, logo, address, warehouse/bank references).
 * - `mapOrganization(org, info)` → form (tolerant PascalCase reads, `Logo_ID.data` = base64)
 * - `organizationBody(form)` / `organizationInfoBody(form)` → request bodies for
 *   `PUT /api/admin/organizations/update` and `PUT /api/admin/organizations/:id/organization-info`
 * - `pickChanged(body, snapshotBody)` → only the keys that differ from the loaded snapshot
 *   (both routes have changed-field semantics; `''` clears a reference)
 * - `saveOrganizationLocation(form)` → C_Location create/update through `/api/settings/locations/*`
