source-chargebee: Unique Behaviors

1. Product Catalog Version-Gated Streams

Chargebee has two incompatible Product Catalog versions (1.0 and 2.0), and many streams only work with one version. When a stream is requested against the wrong Product Catalog version, the API returns a response with api_error_code: configuration_incompatible. The connector silently ignores these responses via a predicate-based error filter rather than failing the sync.

Why this matters: A Chargebee account on Product Catalog 2.0 will silently produce zero records for streams that only exist in Product Catalog 1.0 (like addon), and vice versa. There is no upfront validation of which catalog version the account uses, so streams quietly return empty rather than raising an error explaining the incompatibility.
