Add SharedKeychainManager and migrate token storage from the old iCloud Key-Value (KV) approach to a synchronized Keychain-backed solution. Replace iCloudTokenManager usages across WatchSessionManager, TokenManager, and WatchConnectivityManager, update saveToken API to syncToSharedKeychain, and add KV-store migration logic that moves existing KV entries into the shared Keychain and clears the old KV store. Update entitlements (add keychain-access-groups) for both Runner and the Watch app, add/remove files in the Xcode project, delete iCloudTokenManager.swift. Also include access-group resolution, logging, and compatibility observer methods in the new manager.
