Improve dApp detail page

[Jim8y]

Scope

• Improve the existing dApp detail page only.
• Add clear source information, OneGate catalog status, website host, runtime permission explanation, recent-open state, and localized tags.
• Keep the existing open, favorite, add-to-home, share, screenshots, description, and language flows intact.

Validation

• git diff --check
• iOS simulator: built, installed, opened N3 Governance details from Apps, verified source/permissions/recent activity/tags rendering, and verified Open still launches the dApp WebView.
• Android emulator: built, installed, opened N3 Governance details from Apps, verified source/permissions/recent activity/tags rendering, verified Open launches the dApp WebView, and checked crash buffer was empty.

Screenshots

• Android: https://tmpfiles.org/dl/wnw9dqkL9QyQ/onegate-dapp-detail-android.png

Known limitations

• Recent activity uses the existing local dapps/recent list, so it only indicates whether the app was recently opened on this device.
• Permission details are a runtime explanation; this PR does not add a new permission registry or change dApp execution behavior.

• Android: https://github.com/Jim8y/OneGateApp/releases/download/pr-55-screenshots-20260621/onegate-pr55-android-dapp-detail-latest.png

Verification:

• git diff --check
• Localized resource parity check across all Strings*.resx files: 292 keys each
• iOS simulator build: net10.0-ios, iossimulator-arm64
• Android emulator build: net10.0-android, android-arm64
• iOS Simulator: verified DApp Details renders the metadata cards and that game type is included in Tags (GameFi, 桌游)
• Android emulator: verified DApp Details renders the metadata cards and that game type is included in Tags (GameFi, Board); no OneGate crash entries in crash buffer

Review follow-up:

• Included GameTypeDisplayName in the existing Tags metadata card.
• Removed the standalone Game Type rows from the detail page so the field is not left outside the new metadata layout.
• Added the new DApp detail resource keys to every supported locale.

Pull request overview

Improves the existing dApp detail page UI by adding clearer provenance and contextual metadata (source info, catalog/external status, website host, runtime permission explanation, recent-open state, and localized tags) while preserving existing actions/flows (open, favorite, add-to-home, share, screenshots, description, languages).

Changes:

• Added new localized string resources for dApp source/status, permissions summary, recent activity, and tags (EN + zh-Hans).
• Extended DAppDetailsPage code-behind with computed display properties (hosts/status/tags/recent state) derived from the bound DApp and local settings.
• Refactored DAppDetailsPage XAML layout to present the new metadata in “Card” sections while keeping existing content sections.
