Migration Notes

This SDK has been modernized and contains breaking changes. Highlights below are organized by area.

Build And Tooling

Gradle wrapper upgraded to 9.3.1 (requires Java 17+ to run the build).
Kotlin upgraded to 2.3.0.
Dependency versions are centralized in gradle/libs.versions.toml (Gradle Version Catalog).
jcenter() removed; builds resolve from Maven Central via settings.gradle.

OkHttp upgraded to 5.3.2.
kotlinx.serialization-json upgraded to 1.10.0.
Test stack upgraded to JUnit Jupiter 5.14.2 + AssertJ 3.27.7.
Removed unused/legacy deps: jersey-core, commons-codec, guava, jackson-*, moshi, commons-math3.

TutiApiClient.sendRequest(...) no longer creates a dedicated Thread per request.
- Requests now use OkHttp async Call.enqueue(...).
- Query params are now URL-encoded via HttpUrl (no more manual ?k=v concatenation).
runOnOwnThread was removed.
TutiApiClient.billInquiry(...) now returns okhttp3.Call (instead of Thread).
TutiApiClient.authToken is now @Volatile to avoid stale reads across threads.
HTTP logging is now disabled by default; enable explicitly via TutiApiClient.setHttpLoggingLevel(...).

TutiApiClient() now defaults to https://api.noebs.sd/ for both serverURL (consumer API) and noebsServer (wallet/ws/root routes).

IPIN encryption code no longer depends on jersey Base64 or commons-codec.
- Base64 handling uses Okio (okio.ByteString) instead.
