 - `PDIAP-15838` - Remove Apollo for iOS
   Detail: `project-knowledge/02-work-items/pdiap-15838.md`

+  Current note: active Apollo-removal cleanup and validation; do not merge the PR until the REST backend is deployed to production because GraphQL fallback is still needed. Current follow-up includes Fid4 validation, simulator-vs-device/generated-build configuration checks, and `PicoSDK` upgrade investigation for `SampleApp` because the current setup still brings Apollo transitively.
