fix: Update Swift SDK tests for API changes

- Use EmptyCapability() instead of Bool for capabilities
- Use McpUiToolInputNotificationParams instead of removed type
- Use McpUiResourceMetaCsp for resource meta tests
- Add @mainactor to WKWebViewTransport tests
- Use actor-based state capture for Sendable closure compliance
- Extract async values before XCTAssert calls
