Deduplicate-emails

Following User request to remove duplicate emails

[greptile-apps]

PR Summary

This PR implements case-insensitive email deduplication across the contact management system, ensuring that variations of the same email address (e.g., '[email protected]' and '[email protected]') are treated as identical.

• Added case-insensitive email handle comparison in packages/twenty-server/src/modules/contact-creation-manager/utils/get-unique-contacts-and-handles.util.ts using toLocaleLowerCase()
• Implemented URL normalization and email case standardization in packages/twenty-server/src/engine/api/graphql/workspace-query-runner/factories/query-runner-args.factory.ts
• Added test cases in get-unique-contacts-and-handles.spec.ts to verify case-insensitive email deduplication
• Enhanced error handling for both URL and email processing in the query runner factory

suggestion for long term: should this rather be part of the ORM layer so services (like messaging) or custom apps can also benefit from it?

suggestion for long term: this seems tied to validating the input + casting it. I think we need a robust approach here for FE and BE behavior. Ok with this fix for now

I will do the util

[charlesBochet]

must: this could also be extracted to an util and tested separately :)

As discussed orally:

• let's also do secondaryLinks?
• check company creation, do we lowercase email when extracting the domain from an email?
