feat(sdk-android): snapshot property delegate + feature-scoped files + screen fix (#34)

* rename web to inspect ui

* feat(sdk-android): add camelToSnakeCase conversion

* feat(sdk-android): add snapshot() property delegate with tests

* feat(folio): add feature-scoped sanderling snapshot objects

* refactor(folio): slim FolioApplication to snapshot object references

* fix(folio): rename route snapshot to screen, update spec.ts
