fix: make qdrant-client tests cross-platform compatible

- Updated path expectations in deletePointsByMultipleFilePaths tests to handle both Unix and Windows path formats
- Changed stringContaining() to stringMatching() with regex patterns that accept both / and \ path separators
- Fixed absolute path regex to handle both Unix (/path) and Windows (C:\path) formats
- Resolves Windows platform-unit-test failures in CI
