Blog, custom-field, composable-dashboard, auth-demo and mcp-demo converted

[borisno2]

Parent

#1129 — build spec 9 of the Prisma 8 architecture spec. Lands on the prisma-8 integration branch, not main.

What to build

Five examples converted as above; the blog's access-control test script exercises every path on the Dev database; the composable-dashboard posts page is verified inside the Where vocabulary; the mcp-demo's tool calls are re-run against the new schemas.

Acceptance criteria

• Each example's pnpm generate && pnpm dev runs and its test script (where one exists) passes in CI
• The blog test script covers anonymous, author and non-author reads and writes including internalNotes
• No Prisma 7 spelling remains in the five examples

Blocked by

• Starter and starter-auth converted end to end with e2e green #1170

Delivered by PR #1387, merged to prisma-8. (Merges into a non-default branch do not close linked issues, so closing by hand.)

Worth recording what this conversion found, since none of it was visible to any automated check: an anonymous caller was being treated as signed in because a session wrapper built around an absent identity is truthy (root cause filed as #1397, the documentation instances as #1400); the MCP route handler typed its context option so the documented wiring never compiled; an admin could not write at all because its server action built an anonymous context; and the build tool's strict environment mode was stripping auth variables from tasks that did not declare them.
