Zip code doesn't support international addresses

[willgearty]

The zip code field (address_zip on ContactInfo) currently is hard coded to 5 characters. This means it doesn't support postcodes from outside the US.

I think the proper solution would look something like this:

1. Add a second field address_postcode which supports longer postcodes (e.g., UK postcodes are up to 8 characters long)
2. When a user selects "International" from the state field, the postcode field replaces the zip code field (like how the country field dynamically appears)
3. address_zip and address_postcode would both be optional, but when an address is required, at least one of them would be required for the form to be valid

@willgearty Would extending address_zip to support longer international postal codes work here instead of adding a separate address_postcode field?

[willgearty]

address_zip is assumed in some places to represent a US zip code (e.g., the user map module), so I don't think we want to overload it with other postal codes. I guess the alternative would be to check every place that address_zip is used and generalize the usage to international postal codes.

[deepaksoni47]

Makes sense, thanks for the clarification. I'll proceed with the address_postcode approach.

Hi! I've already implemented a fix for this issue in PR #5850.
I'd love to be assigned so I can get it reviewed and merged.
My implementation includes the model migration, form validators,
JS toggle, custom forms widget, admin search, and user search support.
Could a maintainer please assign this to me?
