Migrate and unify URL tooling in twenty-shared.
We now have:
- isValidHostname which follows our own business rules
- a zod schema that can be re-used in different context and leverages is
isValidHostname
- isValidUrl on top of the zod schema
- a getAbsoluteURl and getHostname on top of the zod schema
I have added a LOT of tests to cover all the cases I've found
