src/components: update FormFieldCompanyAddress v-model type

[maceksimon]

Issue: Currently, the FormFieldCompanyAddress component accepts number type ID as the modelValue prop. However, in data, this will be the object with address fields - value needs to correspond with subsidiary address so that we can determine subsidiaryId.

Solution:

• Update type in FormFieldCompanyAddress component
• Update calculating option values in useSelectedOrganization composable and add behaviour that sets subsidiaryId based on selected address.

Additionally, based on data from endpoint, add optional address pro to Organization type.
