* fix: serialize SSE-KMS metadata when bucket default encryption applies KMS
When a bucket has default SSE-KMS encryption enabled and a file is uploaded
without explicit SSE headers, the encryption was applied correctly but the
SSE-KMS metadata (x-seaweedfs-sse-kms-key) was not serialized. This caused
downloads to fail with "empty SSE-KMS metadata" because the entry's Extended
map stored an empty byte slice.
The existing code already handled this for SSE-S3 bucket defaults
(SerializeSSES3Metadata) but was missing the equivalent call to
SerializeSSEKMSMetadata for the KMS path.
Fixes seaweedfs/seaweedfs#8776
* ci: add KMS integration tests to GitHub Actions
Add a kms-tests.yml workflow that runs on changes to KMS/SSE code with
two jobs:
1. KMS provider tests: starts OpenBao via Docker, runs Go integration
tests in test/kms/ against a real KMS backend
2. S3 KMS e2e tests: starts OpenBao + weed mini built from source, runs
test_s3_kms.sh which covers bucket-default SSE-KMS upload/download
(the exact scenario from #8776)
Supporting changes:
- test/kms/Makefile: add CI targets (test-provider-ci, test-s3-kms-ci)
that manage OpenBao via plain Docker and run weed from source
- test/kms/s3-config-openbao-template.json: S3 config template with
OpenBao KMS provider for weed mini
* refactor: combine SSE-S3 and SSE-KMS metadata serialization into else-if
SSE-S3 and SSE-KMS bucket default encryption are mutually exclusive, so
use a single if/else-if block instead of two independent if blocks.
* Update .github/workflows/kms-tests.yml

* fix(ci): start weed mini from data dir to avoid Docker filer.toml
weed mini reads filer.toml from the current working directory first.
When running from test/kms/, it picked up the Docker-targeted filer.toml
which has dir="/data/filerdb" (a path that doesn't exist in CI), causing
a fatal crash at filer store initialization.
Fix by cd-ing to the data directory before starting weed mini.
Also improve log visibility on failure.
