GET /brief allocated a row on first call (BriefStore.GetOrCreate) — the
one endpoint in the backend where a read performed a persisted write.
The FE retries GETs automatically, so a transient failure could enter
the create path more than once; a lock prevented a duplicate row, but
the safety depended on the lock, not on the endpoint being a query.
Split GetOrCreate into Get (a pure query) and the already-existing
ResetAndCreate (POST /brief/reset owns creation). GET /brief now 404s
when the owner has no brief yet. GET /brief/preview used GetOrCreate
too, so it gets the same Get + 404 treatment, forced by the split.
RB-22 already made BriefStore.load() on the FE tolerate a 404 by
calling reset() once; this ticket is what makes that branch live.
Updated the brief/preview/org-template backend tests that assumed
GET seeded a brief on first call to create one explicitly first, and
added a test that GET 404s and writes no row without the fix (verified
red beforehand). Regenerated the API client (npm run gen:api).

One behavior per test across FE machine/store specs and backend endpoint
tests, so a failure names exactly what broke.

Adds LetterHtml.Render, a pure composer mirroring the FE letter canvas'
class vocabulary, behind two ExcludeFromDescription()'d endpoints
(GET /brief/preview, GET /admin/org-template/{subOrgId}/preview).
Auto-resolvable placeholders pull from seed/case data; unresolved
manual ones render as "[NOG IN TE VULLEN: label]". A sent brief
archives its composed HTML (BriefEntity.ArchivedHtml) so a later
org-template republish never changes it. FE gets a hand-written fetch
adapter (text/html, not JSON) and a "Voorbeeld" button that opens the
preview in a new tab.
