remove nestjs-query from app-token and drop unused createOneAppToken mutation (#22765)

## What

Migrates `app-token` off `@ptc-org/nestjs-query` and removes the
auto-generated `createOneAppToken` mutation, which was unused dead API
surface.

## Why

The `createOneAppToken` mutation was reachable only from the schema — no
frontend query, SDK caller, or test used it. It was also non-functional
(its input couldn't set the token `value`), a leftover from
nestjs-query's default `create.one` being left enabled. Real app tokens
(refresh, password-reset, email-verification, invitation, OAuth,
enterprise) are all created directly via the repository in ~14 services,
none of which touched this mutation.

## Notes

- ⚠️ This removes `AppToken`, `createOneAppToken`,
`CreateAppTokenInput`, and `CreateOneAppTokenInput` from the `/metadata`
schema, so the **api-breaking-changes check will flag it**
