chore: migrate UUID from v4 to v7

[marandaneto]

💡 Motivation and Context

Closes #144
Apple only has uuid v4
AFAIK there's no popular uuid v7 package for iOS
Inspired and adapted from https://github.com/nthState/UUIDV7/tree/main

💚 How did you test it?

Validated here https://uuidgenerator.dev/uuid-validator
