fix: Remove /api/ prefix from all API endpoints

- Fixed double /api/api/ issue in production
- Updated all API files to remove /api/ prefix since baseURL already includes it
- Files fixed: platform.ts, oauth.ts, customDomains.ts, domains.ts, business.ts, sandbox.ts
- Production build will need to be rebuilt after pulling these changes
