SPRXCLT-23: support query params and conditional PUT/DELETE in putEmptyObject

[jonathan-gramain]

Summary

• _createRequestHeader: append query string from params.query to the request path
• putEmptyObject: accept params object (params.headers, params.query); return x-scal-version from PUT response as second callback argument (not the key)
• putEmptyObject: fix non-streaming error handling to propagate expected errors (err.isExpected) rather than always wrapping in InternalError
• deleteWithParams: new method — version-conditional DELETE via params.query.version; avoids changing the existing delete() signature for backward compatibility

Tests

• Test server: support conditional PUT/DELETE (version param, If-None-Match: *), track per-key versions, return x-scal-version in PUT/HEAD responses
• Update existing putEmptyObject and conditional-PUT tests for new signatures
• Add three deleteWithParams tests (matching version, wrong version, absent key)

Motivation

Required by MD-1241 (lib/ring/Lease.js in the metadata service), which uses these capabilities to implement a distributed lease backed by a RING object with atomic acquire, steal, renew, and release.

Test plan

• yarn test passes (existing + new unit tests)
