209-217: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick win

Scope HTTP S3 access to test/local usage. Both examples unconditionally set WT_SDK_S3_ALLOW_HTTP=true, including production guidance. Verify the SDK semantics and keep this disabled or omitted for production profiles.

• README.md#L209-L217: split production and test examples so production does not enable HTTP.
• README_CN.md#L201-L209: apply the same security correction in the Chinese example.
