What is this about?

Move anonymous id from 0x0000000000000000 to to a nil 00000000-0000-0000-0000-000000000000 UUID format. This will allow consistency in ids.

[!IMPORTANT] verify impact on the server side of metrics system

We'll keep this issue aside for now and come back to it once we have the feature that allows to merge two users in MixPanel + BigQuery, probably by end of Q1 2024.
