Simplify sendComplete: remove chatId param and dead refreshFragment logic

sendComplete is only ever called from the message-send path, never the
draft path, so the passed chatId always equals this.chatId. The
refreshFragment branch and this.chatId = chatId assignment were dead
code. Removing them also eliminates the class of bug where an old
chatId could accidentally revert the activity's current chat.

+### Common Build Issues
+
+1. **Missing NDK or incorrect version:**
+   - Error: `ANDROID_NDK_ROOT not set` or native library missing
+   - Solution: Install NDK 27.0.12077973 and set ANDROID_NDK_ROOT environment variable

+- Modifying anything in `jni/` directory
+- Changing NDK version

+
+1. **Setup steps:**
+   - Checks out repository with submodules
+   - Validates Fastlane metadata
+   - Sets up Rust cache (working-directory: jni/deltachat-core-rust)
+   - Sets up Java 17 (Temurin distribution)
+   - Sets up Android SDK
+   - Caches Gradle dependencies

+### Important CI Considerations
+
+- Always validate Gradle wrapper before committing changes
+- Fastlane metadata must be valid (validated in CI)
+- Use `--no-daemon` flag for Gradle in CI environments
+- CI builds use FOSS flavor to avoid Google Services dependencies
