Moves the pin to QQQ 4.1.0-RC.6 and removes the stand-ins RC.6 provides
(classification, client channels, table features, the UI API extension
point). Adds retention rules, wipe markers, legal holds, wipe runs and the
per-record-per-field audit key table; the wipe process (null with marker,
overwrite, keyed hash, delete, archive then wipe) runs in one transaction
per batch, destroying the audit keys with the field updates; the audit
protector and key source (AES-GCM wrapped DEKs, AAD-bound); the backups
warning; canary and wipe-proof tests.
Fixes a key-source bug that zeroed each DEK after returning it.
