Implement dialog handling tests for system-level permission and alert dialogs.

Implement dialog handling tests for system-level permission and alert dialogs.

Test case

15. testBluetoothPermissionDialog() — first-run flow, handle system "Allow Bluetooth?" alert

Implementation

Uses addUIInterruptionMonitor:

addUIInterruptionMonitor(withDescription: "Bluetooth Permission") { alert in
    if alert.buttons["Allow"].exists {
        alert.buttons["Allow"].tap()
        return true
    }
    return false
}

Notes

• System pairing/bonding dialog (CoreBluetooth sheet) is not reliably handled by XCUITest — full pairing flow remains manual
• This test verifies only the permission dialog, not the pairing dialog

Acceptance criteria

• Test passes on first-run or after resetting Bluetooth permission
• Interruption monitor is registered in setUp() and unregistered in tearDown()

• Depends on: Add accessibilityIdentifier to every interactive UI element in the storyboard and Swift code so XCUITest can locate them reliably. #14
