feat(app, ios)!: adopt firebase-ios-sdk 10.4.0

BREAKING CHANGE: You must have an APNS token before calling getToken to
get an FCM token on iOS. Previously it was not required. See documentation
for setAPNSToken if you are using getToken in testing or have disabled
FCM Swizzling, and use setAPNSToken to set a token before using getToken
