fix(github-webhook): handle unsupported event types gracefully

Add validation in manual and normal webhook handlers to reject GitHub
event types other than 'push' and 'pull_request'. Unsupported events
now return a graceful response instead of potentially causing
downstream errors. Includes tests for ping events, unsupported event
types, and unknown events.
