feature: Add Cashfree Payment Provider

[AyushChothe]

Roadmap Task

👉 https://getlago.canny.io/feature-requests/p/payment-provider-add-integration-for-cashfree-payments

Context

Cashfree Payments is India's leading payment gateway, and with Stripe halting the onboarding of new merchants in India due to regulatory constraints, businesses are left with limited alternatives. Ensuring that Cashfree Payments is available to users is essential, as it will expand Lago's accessibility and appeal to Indian companies, broadening its reach within this crucial market.

We at Pyrite Cloud have begun developing the integration with Cashfree Payments. This will help expand our platform's accessibility, especially for Indian businesses, by providing them with a reliable payment gateway as an alternative to Stripe.

Description

Added Cashfree Payment Provider concerning existing Payment Providers. Still Work in Progress.

Hi Team, Can you please review this PR, as the related lago-api PR (getlago/lago-api#2545) ready to merge. @vincent-pochet Can you please look into this?

Thank you!

[jdenquin]

@AyushChothe we are taking a look at it before the end of the week! Sorry for the delay here

[jdenquin]

@AyushChothe can you fix the conflicts ? 🙏

About all this:

1. Sorry it took time @AyushChothe, I'm starting looking into it right now
2. I'll take care of the conflicts no worries
3. I may re-open this PR on our repo and make you as a co-author. Reason is we miss a shares secret token and some CI jobs will inevitably fail for now. Until it's fixed I need to proceed this way

@AyushChothe we're testing on our side and having a look at what you produced.
Thanks you for your work!

I'm finishing some UI adjustments but we're investigating some broken behaviour we spotted during our tests.
While it can take some times, it's on our roadmap and we'll handle that as soon as we can.
We'll let you know about the updates here!
