fix(#223): fix issue on test environment SLF4J + agent warnings

[JosephSanjaya]

📱 Description

This PR fixes SLF4J and Byte Buddy agent warnings that occur when running tests in Android Studio or via Gradle.
These warnings do not affect production builds or the APK. They are specific to the test environment only.

• SLF4J warnings happen because no logging backend was configured; adding slf4j-android resolves this by routing logs to Logcat.
• Byte Buddy agent warnings occur due to dynamic Java agent loading during tests; configuring JVM args (-XX:+EnableDynamicAgentLoading) suppresses the warning.
  ℹ️ Note on EnableDynamicAgentLoading
  Suppressing the warning by enabling dynamic agent loading is safe in our case. It only affects the test JVM environment and has no impact on runtime behavior or production APKs. Disabling the suppression would simply keep printing the warning, but still would not break our tests.
