Migrate account_config.json to oneof-discriminated schema

[nmuesch]

Summary

Migrate account_config.json for klaviyo and ringcentral to the new oneof-discriminated schema. Each entry's type / auth_method discriminator becomes the field name carrying the type-specific config; zero-valued placeholders are dropped.

Semantically equivalent — verified by round-tripping each file through the parsing + validation pipeline and asserting structural equality before and after.
