### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary: In SelectDB Core 3.0.11.2, a Primary Key Bloom Filter page
could fill the remaining 39,828 bytes of the first 5 MiB S3 buffer and then hit
a CreateMultipartUpload failure. The pending buffer retained those bytes while
bytes_appended stayed at 5,203,052. Because the Bloom Filter add error was
ignored, later writes could upload the retained bytes and shift the physical
object by 39,828 bytes.
This PR adds a deterministic S3FileWriter unit test that recreates the exact
boundary through PrimaryKeyBloomFilterIndexWriterImpl. It verifies the full
pending buffer, the 39,828-byte accounting difference, no uploaded part,
propagated IO error, and absence of invalid Bloom Filter footer metadata.
