Prevent Android crashes caused by LINE SDK Keystore failures

✏️ Description:

LINE Android SDK 5.12.0 can crash the host app when Android Keystore key generation fails during background encryptor initialization.

The exception escapes from EncryptorHolder$EncryptorInitializationTask.run():

java.security.ProviderException: Keystore key generation failed
→ StringAesCipher.createAesKey()
→ StringAesCipher.initialize()
→ EncryptorHolder$EncryptorInitializationTask.run()

Upgrade com.linecorp.linesdk:linesdk from 5.12.0 to 5.13.0 to include the upstream crash fix.

The updated SDK catches background initialization exceptions and returns a login error when token persistence fails, allowing the app to handle the failure without crashing.

References:

• Upstream issue: The app crashes with java.security.ProviderException: Keystore key generation failed line/line-sdk-android#186
• Upstream fix: fix: prevent crash when device Keystore fails during token persistence line/line-sdk-android#190

🎥 Screen record:

Not applicable — native dependency update.

📌 Notes:

• The existing React Native wrapper already forwards SDK login errors through Promise rejection.
• An Android native rebuild is required to include the updated SDK.

---

✔️ Tasks:

• Upgrade LINE Android SDK to 5.13.0.
• Verify Gradle selects 5.13.0 in the example app's release runtime dependencies.
• Build the Android library with :xmartlabs_react-native-line:assembleRelease.
• Verify the published SDK AAR contains the initialization exception handler.
• Run TypeScript build, lint, and Prettier checks.

⚠️ Warnings:

• Physical-device login flows and Keystore failure reproduction have not been tested.
