fix(oss): use list() instead of getBucketInfo() in ensureBucket to avoid bundling issue

[octo-patch]

Fixes #6552

Problem

When OSS storage is configured, the application logs the following error on startup:

ReferenceError: name is not defined
    at b.createRequest (.next/server/chunks/55042.js:1:4872)
    at b.getBucketInfo (...)
    at y.ensureBucket (...)

This happens because ali-oss's getBucketInfo() internally references a variable named name in its createRequest() function. In bundled environments (Next.js webpack), this conflicts with JavaScript's implicit global name property — resulting in a ReferenceError every time the application starts with OSS configured.

The error is non-fatal (caught and logged), but confusing: users see an alarming error even though their OSS bucket exists and uploads work fine.

Solution

Replace getBucketInfo() with list({ 'max-keys': 1 }) in the ensureBucket() method of the OSS adapter. The list() call:

• Verifies the bucket is accessible (throws on invalid credentials or missing bucket)
• Does not trigger the name is not defined code path
• Is already used successfully elsewhere in the OSS adapter

Testing

• OSS configuration with valid credentials: list() returns successfully, no error logged
• OSS configuration with invalid bucket name: list() throws an OSS NoSuchBucket error, correctly caught and logged
