FINERACT-2827: Document missing tax component fields

[shubhamchaudhary29]

Description

The tax component API response contains debitAccountType and debitAccount, but these fields were missing from the OpenAPI/Swagger response documentation.

I added the missing fields to the Swagger response model.

Changes

• Added debitAccountType to the response schema
• Added debitAccount to the response schema
• Added the required fields for both objects
• Regenerated the OpenAPI specification

Testing

• Spotless check passed
• Java compilation passed
• OpenAPI generation passed
• Verified that the generated OpenAPI schema contains the two new fields
