refactor: add test-with-server targets to all S3 test directories

- Add test-with-server target to acl, basic, delete, etag Makefiles
- Simplify test-with-server to use TestMain-based server auto-management
- Update tagging, cors, filer_group, retention, remote_cache, sse Makefiles
- Add TEST_PATTERN support for CI/CD parameterized testing
- Remove complex manual server management from test-with-server
- All targets now delegate to TestMain for consistent, simplified server lifecycle
- Backward compatible with existing make targets for manual testing
