fix(platform-objects): surface sys_user phone_number in list views and detail highlights (#3262)

A user created with a phone number (auth.plugins.phoneNumber) had the
number persisted but displayed nowhere: no list view included a
phone_number column, and the slotted sys_user detail page whitelists
its highlight/detail fields, none of which was phone_number. Phone-only
accounts surfaced only their placeholder email, so the identifier
looked lost.

- add phone_number to the all_users and me list view columns
- promote phone_number into the detail-page highlights strip (next to
  email — both are sign-in identifiers) and the highlights dedup list

Field translations already exist, so column/chip labels localize as-is.
Verified end-to-end against the showcase example (create via
/admin/create-user, column shown in All Users, chip shown on the
record detail).

Fixes #3262
