feat: limit free teams platform plan (#1673)

This pull request removes the `id` field from
`IsDocumentPlatformOptions` in `is-document-platform.ts` and updates the
billing logic in `create-team.ts`: platform plan users create their
first team free, but pay for subsequent teams; non-platform users need
an active team subscription if billing is enabled.
