Journaling: search, read and export over JMAP, and the chain check

Phase 4 of the journaling spec.

- inbuxa:JournalEntry/query and /get (sysJournalSearch): filter by time,
  sender, recipient, either, direction, subject words, Message-ID and
  journal, newest first; the whole report only when asked for.
- inbuxa:JournalExport/set (sysJournalExport): a reason is required; a
  ZIP of the matching reports with manifest.csv, exceptions.csv and
  manifest.sha256, up to 10,000 reports and 1 GB.
- inbuxa:JournalVerification/set (sysJournalGet): chains and reports
  rechecked.
- Every search, listing, read, export and check is written to the audit
  log before anything is returned, with existing actions only.
- Catalog entries for the three objects; spec as-built notes.

journal_tests: administrators can't search; a Compliance Officer searches,
lists, reads a report, exports (reason required) and checks the chain;
the officer can't change journals; each of those is in the audit log.

+  reason (`export`), each check (`verify`). No new audit actions, so an
+  older version reads every record.
+- `inbuxa:JournalExport/set` builds the ZIP in the request, like the audit
+  log's export, rather than as a task: at most 10,000 reports and 1 GB,
+  and a search that matches more is refused with the count, to narrow.
+  The ZIP has the reports as `.eml`, `manifest.csv` with the envelope and
+  a SHA-256 per file, `exceptions.csv` for reports that couldn't be read,
+  and `manifest.sha256`.
+- `inbuxa:JournalVerification/set` rechecks the chains and every report
+  against its entry, with `sysJournalGet`.
