Add configureAnchorAssets function

[MissBlue00]

Task

Add a configureAnchorAssets function to manage anchor asset configuration.

Details

• Function signature: configureAnchorAssets(assets: AnchorAsset[]): AnchorConfig
• Map Stellar assets to fiat equivalents
• Configure asset-specific fees and limits
• Store configuration for runtime lookup
• Add AnchorAsset and AnchorConfig interfaces
• Integration point: anchor-service package

Test

Run pnpm --filter @stellar-pay/anchor-service build to verify no TypeScript errors.

I'd like to work on this issue because asset configuration is a foundational part of anchor-based payment infrastructure and benefits from clear typing and maintainable runtime lookup patterns.

My approach would be to implement configureAnchorAssets along with the required interfaces, ensuring Stellar assets can be mapped cleanly to fiat equivalents while supporting asset-specific fees and limits.

I would focus on:

defining AnchorAsset and AnchorConfig interfaces
implementing configuration and runtime lookup behavior
keeping the configuration structure extensible for future anchor integrations
ensuring type safety and consistency across the anchor-service package
verifying the package builds successfully using the existing workspace tooling

Happy to align the implementation with existing project architecture and TypeScript conventions.
