Align document render workspace with real RDM server payloads

Why: Independent review of a81e94a..85428b4 found five contract mismatches
against the RDM server: profile sources document-type/project-default were
dropped, the refusal object {code,message} was ignored, submit receipts were
read as `id` instead of `submissionId`, diagnostics were expected inside
preview/export receipts (they live in a separate diagnostics delivery blob),
and rdm.inspect.tree was treated as recursive although it returns one level.

Evidence: New tests use the server JSON shapes (RenderProfileOptions,
RenderDeliveryReceipt, DocSubmissionRec, rdmRenderDownload, InspectTree); 26
of them fail against the previous implementation. npx vitest run: 35 files,
359 tests passed; npm run build: ok; scripts/check-knip.mjs: unused exports
43 <= 43; git diff --cached --check: clean.

Impact: Rules panel lists all five sources with Chinese labels and keeps the
server's selected default; refusals render readably; a new submission is
auto-selected; diagnostics are fetched via rdm.render.download kind=diagnostics
under a sequence/epoch guard with readable failures and a Chinese receipt
state label; the document tree is walked breadth-first (depth 12, 2000 nodes,
concurrency 4) with a truncation notice. Playwright spec asserts per-node
diagnostic anchors after preview (authored, not run).
