Replace UUIDv4 with Timestamp-based approach for generating unique IDs

[dabruhce]

Issue Description

Currently, use UUIDv4 to generate unique identifiers for our system. While UUIDv4 is a good approach to generate unique IDs, it is complete overkill. Not critical but should default to a ms timestamp-based approach for generating unique identifiers. By using timestamps, we can generate unique IDs that are ordered by time, and there won’t be collisions when run on a users local system. Should be implemented as timestamp being a default behavior and UUID as an override if collisions are an issue.
