Expand GameBridgeServer to include macOS builds to enable viem/Fetch API compatibility. Changes: - GameBridgeServer.cs: Add UNITY_STANDALONE_OSX to compilation directives - GreeBrowserClient.cs: Use GameBridgeServer on macOS instead of file:// URLs - IWebBrowserClient.cs: Include macOS in Dispose() interface requirement - Passport.cs: Call Dispose() for macOS to cleanup GameBridgeServer Background: - viem (used in ts-immutable-sdk 2.12.4+) requires Fetch API - file:// URLs have CORS/Fetch API restrictions - GameBridgeServer serves via http://localhost:51990/ to provide proper origin - Windows already uses this approach (PR #646) - macOS now needs same solution for viem compatibility This resolves the "App stuck in Initialisation" issue on macOS.

Summary
The Sequence SDK requires requests to have a valid origin, but loading
index.htmlviafile://URLs results in a null origin.On iOS/Mac, WKWebView provides loadHTMLString:baseURL: which allows setting a custom base URL as the origin.
On Windows, we use the UnityWebBrowser library which wraps Chromium (CEF). Chromium doesn't have an equivalent mechanism, the origin is derived directly from the loaded URL. Since we can't set a custom origin, this PR introduces GameBridgeServer, a lightweight local HTTP server that serves the GameBridge index.html from
http://localhost:<port>.ID-4221
