Money: private Documents page with admin-only file endpoint

Lists contracts/pension docs with written summaries, an inline viewer and
download at /trackers/money/documents. Files and summaries live on the host
(MONEY_DOCUMENTS_ROOT, bind-mounted read-only by deploy-remote.sh), never in
git or static/; the file endpoint is admin-only (401/403) and private, no-store.

+`/trackers/money/documents` lists private documents (contracts, pension rules) with a
+written summary, an inline viewer and a download. Nothing about them is in git: the
+files and the summaries live on the host in `MONEY_DOCUMENTS_ROOT` (default
+`/money-documents` when it exists, otherwise `~/money-documents`) as
+`documents.json` (`[{ id, title, category, date, pages, file, summary }]`, summary in
+Markdown) plus `files/<file>`. `scripts/deploy-remote.sh` bind-mounts
+`/home/stan/money-documents` read-only at `/money-documents` when it has a
+`documents.json`. Files are only streamed to admins via
+`/trackers/money/documents/<id>/file` (401 logged out, 403 for non-admins,
+`private, no-store`). To add one, copy the file into `files/` and add a manifest entry;
+no redeploy is needed.
