z.union picks the first member that parses successfully, so a body
with { name, parentId } would silently be parsed as a rename and the
parentId dropped. The route comment claimed this was rejected — it
wasn't. Adding .strict() to each branch makes the rejection real:
both members refuse extra keys, the union produces a 400, and the
rep gets feedback instead of a silent half-op.

GET /api/v1/document-folders → full tree (documents.view).
POST /api/v1/document-folders → create (documents.manage_folders).
PATCH /api/v1/document-folders/[id] → rename OR move (union schema —
refuses both in one body so audit logs stay one-op-per-call).
DELETE /api/v1/document-folders/[id] → soft-rescue delete; returns 204.
PATCH passes ctx.userId through to the service-level audit-log
emitters (renameFolder + moveFolder gained userId in Task 4 fixes).
