feat: Auto-Swap Service for STRK Transfers

[Jagadeeshftw]

closes #1

[Jagadeeshftw]

Instead of directly listening for STRK contract events, I’ve added the /auto_swap endpoint. This endpoint receives the required details (from, to, value) via payload, processes the subscription information from the database, and performs the token swap using the EKUBO contract.

Is this approach in line with what you were expecting @Abeeujah?

[Abeeujah]

Yeah, it's an endpoint that receives the payload, just as you mentioned, you were not supposed to listen to events, the issue description mentioned we have an indexer that listens to events... so, you're in line, keep going. 👍

Hi @Abeeujah , I've almost completed it, but a few things are still pending:

1. Update sqrt_ratio_limit based on token0 and token1.
2. Fix an issue with passing calldata to the swap function.
3. Complete testing.
   I'm hoping to have these resolved and will open the PR for review within the next couple of days.

I've done with code changes, after testing I will open it for review.
