Pull request overview

This PR hardens WebView bridge JSON compatibility under obfuscation by adding explicit @SerializedName mappings, and adds unit tests that document/lock in the current behavior of several custom GSON adapters used by the SDK’s operation models.

Changes:

• Added @SerializedName annotations to WebView bridge messages and payload DTOs to ensure stable JSON keys.
• Added new unit tests covering read/write/round-trip behavior for multiple GSON TypeAdapters (DateOnly, DateTime, Ids, CustomFields, ProductList response polymorphism, MindboxError).
• Tightened consumer-rules.pro keep rules (narrower in-app DTO scope; removed overly broad Preference keep rule).
