Feat/dodo products creation

[0xanshu]

This pull request refactors and improves the onboarding flow for Dodo Payments integration. The main changes are automatic creation of product IDs during onboarding (instead of requiring them from the user), better error handling for common Dodo Payments API errors, and stricter, normalized validation of the currency field. These changes simplify the onboarding process and make it more robust.

Onboarding Flow Improvements:

• Product IDs for Dodo Payments (dodo_live_product_id, dodo_test_product_id) are now created automatically during onboarding, rather than being provided by the user. The code creates both live and test products and stores their IDs.
• Webhook creation for both live and test environments is performed in parallel, and the webhook URLs have been updated to a new endpoint (createCheckout).

Validation and Schema Updates:

• The currency field in onboardingSchema is now a strict enum (usd, eur, gbp, inr, jpy) and is mapped to uppercase codes for consistency.

Error Handling Improvements:

• Adds specific error handling for AuthenticationError and BadRequestError from the Dodo Payments SDK, returning clearer error messages to the user when onboarding fails due to invalid API keys or configuration issues.

These changes make onboarding with Dodo Payments more user-friendly and reliable.

T-Rex Logs

What T-Rex did

• I ran the pre-artifact onboarding currency schema test to compare legacy behavior.
• The pre-artifact run showed legacy behavior where arbitrary or uppercase currency strings were accepted without normalization, and caller-supplied product IDs were required.
• I ran the post-artifact onboarding currency schema test and confirmed 12 passing assertions, including stricter enum validation, uppercase normalization, and an uppercase USD in the mirrored payload shape.
• I captured and attached artifacts including the two test logs and the TypeScript test definitions to help inspectors verify the changes.
