Improve gaming hub experience

[Jim8y]

Scope

• Add a focused Gaming Hub status card with wallet connection state and game catalog readiness.
• Add a Recently played row for gaming dApps using the existing local dapps/recent history.
• Improve the Gaming empty/loading presentation without changing game execution or dApp runtime behavior.
• Refresh Gaming Hub recents when a gaming dApp is opened.

Validation

• iOS Simulator: dotnet build OneGateApp/OneGateApp.csproj -f net10.0-ios -p:RuntimeIdentifier=iossimulator-arm64 -p:BuildIpa=false -p:EnableCodeSigning=false
• iOS Simulator: installed and launched on iPhone 17 Pro / iOS 26.5, opened Gaming, opened Pixudi, returned to verify Recently played.
• Android Emulator: dotnet build OneGateApp/OneGateApp.csproj -f net10.0-android -p:RuntimeIdentifier=android-arm64 -p:AndroidSdkDirectory=/opt/homebrew/share/android-commandlinetools -p:JavaSdkDirectory=/opt/homebrew/Cellar/openjdk@17/17.0.19/libexec/openjdk.jdk/Contents/Home -p:EmbedAssembliesIntoApk=true
• Android Emulator: installed and launched on emulator-5554, opened Gaming, verified wallet/game status and Recently played.
• Android crash buffer: empty after validation.

Known limitations

• This PR does not change the WebView/game runtime. Individual game content still depends on the upstream dApp loading successfully. During iOS validation, Pixudi opened and updated Hub recents, but its remote page content did not finish rendering before returning to Gaming.

• iOS simulator build: net10.0-ios, iossimulator-arm64
• Android emulator build: net10.0-android, android-arm64
• iOS Simulator: launched and verified the Gaming tab after the review fix

Review follow-up:

• Removed the wallet/catalog status card that duplicated low-value information.
• Reworked the recently played game cards with fixed height and centered icon layout.

Pull request overview

This PR enhances the Gaming hub UI by adding a status card (wallet connection + catalog readiness), introducing a “Recently played” row powered by the existing dapps/recent history, improving the empty/loading presentation, and refreshing hub state after launching a gaming dApp.

Changes:

• Add new localized strings for Gaming hub status/empty/recents.
• Update GamingPage to load recent IDs from settings, compute status text, and expose a recent-games collection for XAML binding.
• Invalidate GamingPage recents after opening a gaming dApp so the hub refreshes on return.
