Migrate url tooling to twenty-shared (#10440)

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

Also fixes: https://github.com/twentyhq/twenty/issues/10147
