6dc6a0b9a2 MUL-7650: attachment viewer — CSV tables, JSON/YAML tree, numbered code, HTML viewports, every kind in a new tab (#8868)
* feat(server): accept JSON Lines in the attachment text preview proxy

The viewer now shows .jsonl / .ndjson files as a tree, so the text proxy's
whitelist takes them too (extension and application/x-ndjson). The whitelist
test gains the CSV / TSV / log / JSON Lines cases and says it is mirrored by
the client-side table in packages/views/editor/utils/preview.test.ts.

* feat(views): table, tree, numbered-line and viewport views in the attachment viewer

MUL-7650, step 3 of MUL-7642. Fills in how the full-window viewer shows the
file types agents produce most.

- CSV / TSV (`table` kind): parsed to a table on the shared DataTable —
  pinned header, virtualized rows, resizable columns, a frozen row-number
  column. Clicking a header sorts ascending / descending / file order;
  numbers sort numerically, empty cells stay last, all-number columns align
  right. `;`-separated exports are sniffed. DataTable headers now carry
  aria-sort when the table sorts through TanStack's own state.
- JSON / JSON Lines / YAML (`structured` kind): a collapsible tree with
  inline previews of collapsed records and paged long lists; Tree / Raw in
  the top bar. A file that does not parse falls back to the source and says
  why. YAML alias expansion stays capped by the parser.
- Code, text and logs: numbered lines (the number is a pseudo-element, so
  copying skips it) with a sticky gutter, and a wrap toggle. Logs and plain
  text wrap by default, code does not; the reader's choice carries across
  the sequence.
- HTML: Fit / Desktop 1440 / Tablet 768 / Phone 390. A device width lays the
  document out at that width and scales it down when the stage is narrower,
  with the size and scale shown under it; switching never remounts the
  iframe. A source toggle shows the HTML with line numbers.
- Open in new tab works for every previewable kind: /{slug}/attachments/{id}
  /preview loads the record by id and renders the viewer's own top bar and
  stage (AttachmentPreviewStandalone), keeping the desktop scroll restore for
  HTML.
- Whitelist: .jsonl / .ndjson join the text types on both sides, and the
  client test mirrors the server's case table.
