Android theme properties not applied (card background, card border, checkbox tint)

[ievitchenko]

SDK: @sumsub/react-native-mobilesdk-module
Platforms tested: iOS (works correctly), Android (theme partially ignored)
Issue type: Theme not applied / inconsistent behavior between iOS and Android

Description
When providing the same theme object for both iOS and Android, the UI looks correct on iOS but Android ignores several theme properties, resulting in visual inconsistencies.

Specifically:
Cards
On iOS: background and border styling is applied correctly.
On Android: cards still appear with the default transparent background and default border, even when the same values are passed.
Adding an explicit android.colors block does not change the result.
Checkbox tint (fieldTint)
On iOS: the checkbox correctly changes color according to fieldTint.
On Android: the checkbox remains system default blue, regardless of the value provided in fieldTint.

IOS:

Android:

Request
Can you please confirm:
Are these theme properties currently supported on Android?
Is there a workaround for applying: card background, card border, checkbox tint on Android?
