Jakob Wennberg 4501f118c2 feat(mcp): approval-queue MCP Apps widget for staged operations (#1278)
* feat(mcp): approval-queue MCP Apps widget for staged operations

gnubok_list_pending_operations(render_ui=true) now renders an interactive
approval queue (claude.ai / Claude Desktop) where the user approves or
rejects each staged operation with a click. High-risk operations arm the
approve button and the second click sends confirmed=true, so the BFL
5 kap 5 acknowledgment is a first-party human action instead of the
agent asserting confirmed=true on the user's behalf (the audit weakness
flagged in dev_docs/erpclaw_analysis.md).

- New widget ui://pending-operations/app.html following the established
  self-contained postMessage/JSON-RPC pattern (no fetch, theme-aware,
  Swedish labels, expandable preview_data per row).
- Result-level _meta.ui hint gated on render_ui=true, mirroring the VAT
  report wiring; the tool stays data-only by default.
- Widget tool references project per namespace (accounted_* clients see
  accounted_ names inside the HTML).
- tools/list payload ceiling 58K -> 58.5K per the in-test convention:
  prose trimmed to the floor first, remainder is wire contract.

* fix(mcp): time out the widget RPC bridge so a silent host cannot strand a row

Review follow-up: sendRequest never settled if the host dropped a
response, leaving op._working=true forever with the approve/reject
buttons gone. A 30s timeout rejects the promise; the existing catch
paths restore the row with an error message so the user can retry.
