Linus Rath 530364b11c fix: stop a cancelled or wiped export from downloading, and say why an export stopped
Review of the local store export. A cancel, sign-out or wipe during the
final step still downloaded the file; now the sink takes the job's signal
and drops the Blob, and a job that outlasts the wait is forgotten when it
ends. Finished exports are in a list a later wipe or sign-out can empty,
also after the dialog closed.

- `localExportAllowed` uses `scopeDecided`, so a domain or group scope
  can't be missed before the subject arrives. It's checked before the
  save picker, in the same tick as the click.
- WebKit holds the final Blob in memory: exports stop at 1 GB, and a
  larger choice or one over `storage.estimate()` is refused up front.
- An empty folder that refuses during a full listing counts as empty,
  only when the store's own count agrees. Any other refusal stops the run.
- A picked file goes on an abort or an all-failed run; if it can't, the
  dialog names it. Failure texts come from our strings, not the browser's.
- A selection keeps to the chosen folders on a retry.

The test that the organisation shows as the reason now flips the policy
through the policy store, because the old one replaced the guard and so
never reached the watch that a real change goes through. The spec moves
to an account of its own, dso-export: other specs running at the same
time work in ent-dave, and its folder went missing there mid-run.

Linus Rath e80f5ade81 feat: let admins turn off downloads, export, printing and the install prompt, and add a watermark
Organisation > Devices now sets policy.json `organisation.devices`, each
switch off by default and scoped per domain or group:

- No downloads: attachments and files only preview (reader, conversation
  view, Pro tab, list chips, .eml previews, the Files app). Download,
  Download all, Open in new tab, Save to Files, drag-out, the browser's
  PDF viewer (pdf.js instead) and media download controls go away.
- No export: no .eml export, View source, message drag-out, or folder and
  account export; a running export stops and its file is deleted when
  the switch turns on. Import stays.
- No printing: no Print buttons in mail, calendar and contacts; Ctrl+P
  prints a note; the reader frame prints blank.
- No install prompt: no card, and the browser's own banner is held back.
- Watermark: the user's address and the date over the reader,
  previews and every printout (mail, calendar, contacts, plugins).

A message follows its own account's policy; what isn't about one message
follows the strictest signed-in account. Every user path hides its
button, and the anchor and new-tab helpers refuse as a backstop
(lib/download-guard.ts), never the blob readers. The plugin APIs
`ui.downloadFile` and `ui.print` refuse too, and the office editor frame
loses `allow-downloads`.

Two assertions in components/mail/__tests__/blob-routing.test.tsx now
expect `{ kind: 'export' }` as the fifth argument of downloadBlob for an
.eml export: the export says what it is, so the backstop checks "No
export" rather than "No downloads" for it.
