T22/T24/T26: uploader, integration tests, and release readiness

T22 -- TelemetryUploader on package:http with MockClient standing in for
MockWebServer, tested against a real in-memory Drift database rather than a fake
DAO. Upload runs on its own timer, injected as a callback so the engine has no
opinion about HTTP and tests need no network. Config on shared_preferences with
a hand-rolled UUID v4. Still no UI for the endpoint, exactly as in the native
app. 7 tests.

T24 -- integration_test/app_test.dart, 4 tests passing on the iOS simulator.
These cover what widget tests cannot: Drift opening against real platform
storage, plugin registration, go_router driving a real Navigator, cold start.

T26 -- RELEASE-IOS.md. Usage strings are specific rather than generic, which is
the leading Guideline 5.1.1 rejection cause; privacy-label answers decided; a
pre-submission list covering the bundle-id switch back to com.rippr, the still
default app icon, a release build, and a demo video for review notes.

T25 written up as REAL-RIDE-CHECKLIST.md but outstanding by nature. Two items
decide real things: force-stopping mid-ride on Android confirms the 111 km
crash-gap bug is fixed, and parking 15 minutes mid-recording on iOS decides
whether geolocator is sufficient or the paid engine is needed.

Two prefer_initializing_formals lints suppressed with a reason: Dart forbids a
named parameter beginning with an underscore, so the suggested fix will not
compile.

178 tests passing, analyze clean.
