feat: integrate OneKey hardware wallet over BLE (hd-ble-sdk)

[wabicai]

Summary

Add OneKey hardware wallet support via Bluetooth Low Energy (BLE) for Bitcoin Keeper.

Architecture

Modal-based Interaction (OneKeyBleModal)

All primary OneKey flows use OneKeyBleModal - a self-contained modal component:

• Setup: Scan → Select device → Connect → Import keys
• Health Check: Direct connect via stored bleConnectId → Verify fingerprint
• Verify Address: Direct connect → Show address on device → Compare

Dedicated Screens (transaction flows)

• SignWithOneKeyBle - PSBT signing (auto-connects via stored connectId)
• SignMessageOneKeyBle - Message signing (auto-connects via stored connectId)

SDK UI Event System

• onekeyUIEmitter (DeviceEventEmitter) forwards SDK UI events to components
• PIN request → "Please enter PIN on your OneKey device"
• Button confirm → "Please confirm on your OneKey device"
• Passphrase → "Please enter passphrase on your OneKey device"
• Events auto-clear after each operation completes

Device Reconnection

• bleConnectId stored in signer.extraData during setup
• All subsequent flows use stored connectId for direct connection
• Brief BLE scan before connect (required by BLE protocol)
• 30s timeout on all BLE operations

Dependencies

• @onekeyfe/hd-ble-sdk - BLE transport for React Native
• @onekeyfe/hd-core - SDK core (UI_EVENT, UI_REQUEST, UI_RESPONSE)
• @onekeyfe/hd-shared - Shared types and error codes
• @onekeyfe/hd-transport-react-native - RN transport layer

Signer Naming

• signerName: Device type (e.g. "OneKey Pro")
• signerDescription: BLE name (e.g. "Pro 04DD")
• extraData.bleConnectId: Stored for reconnection

Error Handling

• PIN incorrect (code 801) → friendly toast
• PIN cancelled (code 802) → friendly toast
• BLE timeout (30s) → "Device not found"
• No stored connectId → "Please re-add this device"

Smoke Test Checklist

Setup

• Hardware Keys → OneKey → "Setting up OneKey" modal with illustration
• Proceed → Scan finds devices with correct images and BLE names
• Tap device → PIN prompt if needed → Keys imported
• Keys page shows "OneKey Pro" + "Pro 04DD" with green icon

Health Check

• Keys → OneKey device → Details → Health Check
• Verify OneKey modal → Proceed → Direct connect (no device list)
• Loading: Connecting → Verifying → Success toast

Address Verification

• Vault → Receive → Verify Address → Select OneKey signer
• Modal → Direct connect → Address shown on device → Match result

Transaction Signing

• Vault → Send → Sign → OneKey → Auto-connects → Signs PSBT

Message Signing

• Details → Sign Message → Auto-connects → Signs → Returns signature
