The integration server was pinned to `stalwartlabs/stalwart:v0.16`. The
image is now the `STALWART_IMAGE` build argument (same default), passed
through `docker-compose.yml` and `integration/run-tests.sh`.
Stalwart 1.0 answers Principal/query with `forbidden` unless the Sharing
setting `allowDirectoryQueries` is on, which would stop the shared-folder
specs in their setup. The account plan turns it on (0.16 has the same
setting), and `principalIdByEmail` reports such a refusal clearly instead
of failing on an undefined list.
Add an end-to-end integration harness that runs the webmail against a real
Stalwart mail server in Docker and drives it with Playwright, focused on the
mail/folder synchronisation behaviour (unread/total counters, folder-list
sync, account-scoped Unified Mailbox) that the unified-mailbox work touches.
- integration/ stack: Stalwart (declarative bootstrap: alice/bob/carol,
submission + IMAP listeners, permissive CORS) + webmail (dev mode, so the
browser's plaintext cross-origin JMAP calls aren't blocked by the prod CSP).
- Helpers: dependency-free SMTP submit client, JMAP client for seeding /
inspecting server state, and page helpers (login, add/switch account,
locale-independent folder-counter reads).
- Specs: login, single-account sync (receive/read/move/delete/folder-create/
burst) and multi-account (per-account isolation + cross-account Unified
Inbox aggregation + background-account delivery). 12 tests, all green.
- Add focused data-testid hooks to the mail UI (folder rows + counters, email
list items, account switcher, composer) for stable selectors.
- Exclude examples/ and integration/ from tsconfig/eslint/.dockerignore.
