Fixed using Opus 4.7, I wanted to test this model out and in this repo I
know you guys care about quality, pls let me know if this is good code.
It looks good to me
Fixes#19740.
## Summary
PostgreSQL UNIQUE indexes treat two `''` values as duplicates but two
`NULL`s as distinct. `validateAndInferPhoneInput` was persisting blank
`primaryPhoneNumber` as `''` instead of `NULL`, so a second record with
an empty unique phone failed with a constraint violation. The sibling
composite transforms (`transformEmailsValue`, `removeEmptyLinks`,
`transformTextField`) already canonicalize null-equivalent values;
phones was the outlier.
- Empty-string phone sub-fields now normalize to `null`. `undefined` is
preserved so partial updates leave columns the user did not touch alone.
- `PhonesFieldGraphQLInput` drops the aspirational `CountryCode` brand
on input. GraphQL delivers raw strings at the boundary; branding happens
during validation.
