* ♻️ Rename audit-log archivers to consumers
The pending-queue owners are no longer only external archives: a
local, non-archiving drain is about to join them, so "archiver" no
longer fits. Rename the column, identifiers, jobs, metrics and docs
to "consumer" in one release; migration 0157 never reached
production, so a single RENAME COLUMN is enough, with no backfill.

* ♻️ Use base Nexus URI with appended ingest path
Mirror the admin-console setup: PENPOT_NEXUS_URI holds the base
URI and the consumer appends api/audit itself, instead of a full
endpoint URI. Keeps the explicit :uri job param as override and the
:task-not-configured guard when no base is set.
