phase-6: the staff console, and a log that says who did what

Flow H, three screens behind a role check: find an account, work the
ingestion error queue, read and export the audit log. Superadmins can
change a role, never their own.

The error queue merges ingest errors and dead jobs into one table with a
cursor that pages both sources; only a job can be retried and only an
ingest row resolved, with a note that migration 003 gives it somewhere
to live.

writeAudit no longer defaults a missing subject to the actor, which had
been recording a user search as staff looking themselves up. Omitting
the subject still means acting on yourself; null now means the action
has no subject, which is what a search, a retry and an export are.

Reading the log is not audited. Exporting it is: a copy leaving the
building is a different act from looking.

e2e/global-setup.ts asks for every screen once before the suite starts,
so a dev server's first-request compile is paid before the first test
rather than by it.
