feat(sdks): enable fixes.openSingleValueEnumsOct2026 across all SDKs

Enable `fixes.openSingleValueEnumsOct2026: true` in `.speakeasy/gen.yaml` across all SDKs (Python, TypeScript, Go, Java, .NET, and CLI) and regenerate so single-value response enums (`EnvironmentNetworkEnum`, `Language`, `NetworkEnum`, `Disabled`, and `ImageResponseFormatMimeType`) are marked open and tolerate unknown server-returned values without failing deserialization. Union discriminator tag enums remain closed.
