chore(proguard): Add rules for DeviceInfo and Moshi

This commit updates the ProGuard rules to ensure proper functionality in release builds.

- A rule has been added to keep all members of the `DeviceInfo` helper class, preventing obfuscation from removing fields used for device information gathering.
- Rules for Moshi and Kotlin Metadata have been included to support reflection, which is necessary for JSON serialization/deserialization of data classes.
