Add Activity Center

[Jim8y]

Scope

• Add a focused Activity Center page under Settings.
• Record local dApp activity for launches/connections, wallet authorization, message/transaction signing, submitted transactions, and OneGate Vault transactions.
• Keep records in the existing Settings store as a capped local timeline, avoiding schema migration and unrelated page refactors.

Validation

• git diff --check
• Localized resource parity check across all Strings*.resx files: 310 keys each
• iOS simulator build: net10.0-ios, iossimulator-arm64
• Android emulator build: net10.0-android, android-arm64
• iOS Simulator: opened Settings > Activity Center and verified the activity summary/timeline renders with OneGate Vault wording
• Android Emulator: opened Settings > Activity Center and verified the activity summary/timeline renders with OneGate Vault wording; no OneGate crash entries in crash buffer

Screenshots

• iOS: https://github.com/Jim8y/OneGateApp/releases/download/pr-53-screenshots-20260621/onegate-pr53-ios-activity-center-latest.png
• Android: https://github.com/Jim8y/OneGateApp/releases/download/pr-53-screenshots-20260621/onegate-pr53-android-activity-center-latest.png

Review follow-up

• ActivityLogService.GetRecentAsync() now catches corrupt/incompatible local Settings data and returns an empty list instead of crashing Settings/Activity Center.
• Renamed the unclear VaultOperation activity type to OneGateVaultTransaction and updated visible copy to OneGate Vault transaction wording.
• Added the new Activity Center resource keys to every supported locale.

Known limitations

• The timeline is local to the device and does not backfill historical chain transactions.
• Records are capped to the latest 50 entries to keep Settings storage small.
• The PR intentionally does not change Home Dashboard, Global Search, or dApp detail pages.

What is VaultOperation?

[Copilot]

Pull request overview

Adds a new Settings subpage (“Activity Center”) that records and displays recent on-device wallet/dApp actions (connections, authorizations, signatures, submitted transactions, and Vault operations) using the existing Settings key/value store.

Changes:

• Introduces a local activity timeline model + persistence service (capped to the latest 50 records).
• Adds a new Activity Center page (UI + summary counters) and wires it into Shell routing and Settings.
• Hooks activity recording into dApp launch, wallet authorization, signing, and transaction relay flows.

@erikzhang addressed the naming: VaultOperation was too vague, so I renamed the activity kind to OneGateVaultTransaction and changed the visible copy to “OneGate Vault transaction” / “OneGate Vault”. The updated iOS and Android screenshots in the PR show the clearer wording.

Latest review follow-up after merging current master (bb40f15): the outdated Copilot concern is already addressed by 6c66a62, and the branch now includes merge commit c7b92c8.

Review handling:

• ActivityLogService.GetRecentAsync() catches corrupt or incompatible local activity history and returns an empty list, so Settings and Activity Center do not crash on bad local data.
• Activity logging remains diagnostic and does not block wallet operations.

Validation:

• git diff --check origin/master...HEAD passed.
• Conflict-marker scan passed.
• iOS simulator build/install/Settings → Activity Center verified.
• Android emulator build/install/Settings → Activity Center verified with empty crash log.

Refreshed screenshots:

• iOS Activity Center
• Android Activity Center
