web/satellite/src/api: Absorb analytics errors

Browse Source 
On more privacy-sensitive browsers, attempts to notify the satellite
about client-side events might be blocked, because the API endpoint on
the satellite contains the word "analytics".

We want to respect the privacy of these types of visitors, so rather
than changing the name of the endpoint to something else, this change
catches errors that are caused by attempting to use the analytics API,
and logs them to the console without interrupting the user's experience
of the website. These errors do not affect any essential behavior, so it
is okay if the user is not aware of them.
