fix(onramp): suppress Bugsnag reporting for user-caused onramp web errors

CoinbaseOnRampWebError extends plain Throwable, so ErrorUtils.handleError
falls through to `throwableCause !is CodeServerError` which defaults
isNotifiable to true — causing every user-caused error (card declines,
region mismatches, GPay not supported, etc.) to be reported to Bugsnag.

Make the base sealed class implement ConditionallyNotifiable with
isNotifiable = false. Subclasses representing genuine unexpected failures
(UnknownFailure, InternalFailure, SendFailed, ProcessingFailed) retain
NotifiableError with an explicit override.
