Builds the network foundation for the Wear OS vertical PoC: OkHttp-based UploadClient mirroring doctate-client-core's wire protocol (multipart /api/upload, X-API-Key, transient/terminal classification), BuildConfig-backed Settings sourced from local.properties, CaseId factory, DoctateApp service locator, MockWebServer-based UploadClientTest for wire-format assertions, plus the manifest/permissions/network-security- config plumbing for emulator-loopback cleartext. MainActivity is still the placeholder UI; audio recording, ViewModel, and recording screen come in follow-up commits.
