fix(notifications): cancel on missing channels and Twilio 4xx errors (#9254)
# Which Problems Are Solved

#9185 changed that if a notification channel was not present,
notification workers would no longer retry to send the notification and
would also cancel in case Twilio would return a 4xx error.
However, this would not affect the "legacy" mode.

# How the Problems Are Solved

- Handle `CancelError` in legacy notifier as not failed (event).

# Additional Changes

None

# Additional Context

- relates to #9185 
- requires back port to 2.66.x and 2.67.x
