fix(showcase): stop passing a non-existent org column when seeding the phone demo user (#3408)

The approval demo's `ensurePhoneDemoUser` inserted `sys_user` with an
`organization_id` key. `sys_user` has no such field — not in the object
definition (25 fields, none org/tenant) and not physically (26 columns, no
`organization_id`); org membership lives on `sys_member`. The key is not
dropped on the way down: it reaches SQL as a real column and the insert dies
with `table sys_user has no column named organization_id`.

The insert is wrapped in a best-effort try/catch, so this surfaced only as a
warn line and an ERROR in the boot log — and the demo user was **never**
provisioned on any boot, leaving the phone surfaces (#3358 §6 "Phone sign-in
surfaces": All Users list, record detail) empty with nothing to look at.

Also drop the dead `admin.organization_id` read in `run`: the same missing
field made it permanently `undefined`, so only the `sys_member` fallback ever
ran. Resolve from `sys_member` directly and correct the comment, which claimed
the column existed but was null.

Verified on a wiped dev DB: boot log goes from 1 ERROR to 0, and
`sys_user` now holds `usr_showcase_phone_demo` / `Mei Phone (demo)` /
`+8613800138000`. Approval fixtures unaffected (2 pending requests + 3 admin
positions still stamped with the org). `tsc --noEmit` passes.

Follow-up to #3364; found while collecting evidence for #3358 §1.
