feat: migrate admin features to gettext

Migrates all admin-related flash messages to gettext for internationalization:
- Admin.UserLive.Index: user deletion messages
- Admin.OrgLive.Index: organization deletion messages
- UserAuth: impersonation start/stop messages

Adds Gettext backend and helpers import to UserAuth module to support translations.

All admin and auth tests passing (87 tests).
