[Due for payment 2026-03-31] [ECUK In-App 3DS] [App] Extend MultifactorAuthenticationContext to include Passkeys factor

[dariusz-biela]

Part of Adding biometric 3DS authentication for Expensify Cards

Implement part of this section of the design doc.

Extend MultifactorAuthenticationContext to support Passkeys as an additional factor entry point by wiring in the new usePasskeysBiometrics hook.

• Update MultifactorAuthenticationContext to include Passkeys as a factor entry point

  • Use the new usePasskeysBiometrics hook as the implementation for Passkeys-related actions/state (see [Due for payment 2026-03-31] [ECUK In-App 3DS] [App] Add usePasskeysBiometrics hook and WebAuthn helpers #79464)

• Gate Passkeys flows so they are available only when all conditions are met:

  • The current browser/device environment supports WebAuthn
  • The current Scenario configuration enables Passkeys

• Update Scenario configuration to add a Passkeys flag

  • For now, keep Passkeys disabled in all scenarios (i.e., configuration should exist, but feature remains blocked everywhere)

We plan to work on it, but the native biometrics issues need to be completed first.
