fix(server): correct OpenAPI schema for phones.additionalPhones (#20631)

Fixes #20629

Problem

The OpenAPI schema for PHONES composite fields documented
additionalPhones as string[], but the actual runtime type (defined in
phones.composite-type.ts) is Array<{ number: string, countryCode:
string, callingCode: string }>. This caused generated SDK types and API
docs for create/update payloads to be incorrect.

Root cause

A hardcoded mistake in
convert-object-metadata-to-schema-properties.util.ts — the
FieldMetadataType.PHONES branch set additionalPhones.items to { type:
'string' } instead of an object schema.

Changes


packages/twenty-server/src/engine/utils/convert-object-metadata-to-schema-properties.util.ts
- Changed additionalPhones.items from { type: 'string' } to { type:
'object', properties: { number, countryCode, callingCode } }, matching
AdditionalPhoneMetadata.


packages/twenty-server/src/engine/core-modules/open-api/utils/__tests__/components.utils.spec.ts
- Updated all three inline snapshot occurrences (for ObjectName,
ObjectNameForResponse, ObjectNameForUpdate) to expect the correct object
shape instead of string.
