[BACKEND] Async Batching for On-Chain Updates

[Sadeequ]

Goal: Save on Stellar transaction fees by grouping updates.

Task: Instead of 1 transaction per price, wait 5 seconds and send NGN, KES, and GHS in a single "Bundle" transaction.

Hi! 👋
Please, can you assign me this task? I’d love to implement the async batching logic to group price updates into a single bundled transaction, reducing on-chain costs and improving efficiency. I can design a reliable batching mechanism with a timed window (5 seconds), ensure proper aggregation for NGN, KES, and GHS, and handle edge cases like partial failures or retries 🚀
