Stefan HildebrandtandLinus Rath 2fac6ebfb8 test: add characterisation tests for untested integration seams
Golden-master tests pinning the CURRENT behavior of high-value modules
that had no coverage — integration seams, security helpers, two API
route handlers, and complex pure utils. 111 tests across 12 files.

New tests:
- auth-crypto / session-cookie: AES-256-GCM session encryption roundtrip,
  tamper/version/missing-secret handling; cookie-slot naming.
- unified-mailbox: multi-account fan-out, sort, totals, per-account error
  isolation, personal-vs-shared JMAP target resolution, counts/roles.
- account-state-manager: snapshot/restore across the six real Zustand
  stores; clearAllStores reset shape; evict.
- mdn: RFC 5322 MDN assembly (CRLF, RFC2047, base64 wrap, headers).
- tnef: winmail.dat binary parsing from hand-built fixtures.
- download-filename / subject-prefix / birthday-calendar / eml-import:
  filename templating, multilingual prefix stripping, birthday event
  generation, .eml/.zip import.
- webdav / caldav-discover route handlers: auth guards, path validation,
  upstream URL construction, candidate probing.
- helpers/factories.ts: shared makeEmail/makeMailbox/makeFakeJmapClient.

Tests follow the repo's existing patterns (route-import, fake IJMAPClient,
fetch spy, real store singletons). Where current behavior looks buggy it
is pinned and flagged with a // CHARACTERISATION: comment (see PR for the
suspected-bugs list); no production code is changed.
