Summary

Lets merchants override the display name and logo of payment methods in Dynamic Checkout via a new paymentMethodsOverrides config option.

Changes

• New paymentMethodsOverrides option, keyed by "card" or APM gateway_name (same keying as additionalData), each entry { displayName?, logoUrl? }
• getPaymentMethodDisplayOverride() on DynamicCheckoutPaymentConfig resolves the override for a key
• Applied to card, APM, native APM and saved APM payment methods (label, logo, and the "Continue with …" button)
• For APM / saved APM the override logo is also passed to ActionHandlerOptions; gateway_name stays untouched since it selects the flow

Additional Context

• Overrides come from merchant-written JS, so they're treated as untrusted. Any malformed value (non-object root, array, wrong field types, empty strings, inherited keys like __proto__) falls back to "no override" instead of throwing and breaking checkout
• Unset fields fall back to the existing defaults from the API response / translations
