fix(s3): support virtual-hosted-style URLs for S3 storages

Add a "Use path-style URLs" setting to S3 storages. It is detected from
the endpoint (Alibaba OSS, Tencent COS, Volcengine/BytePlus TOS), and the
connection test switches to virtual-hosted style when the provider
rejects path-style requests. Backups pass `--path off` to mc.

Closes #10347
