Never-redact list: protect specific names from every redaction pass

A list of names, addresses or terms that must never be redacted, regardless of what a word list, Auto-Redact or Search & Redact would otherwise match.

Why

The requester's own name has to survive redaction, and so do things like the organisation's name or a case reference. Today a broad word list or Auto-Redact can catch them, and the only fix is to spot it and remove the redaction by hand — on every item.

The ask

A project-level "never redact" list that every redaction method respects. Simpler and independent of automatic name discovery, and useful on its own.

Asked twice in support ("How do I use a whitelist of names that should not be redacted ever?" and "How do I whitelist certain names and email addresses which I don't want to redact?"). Logged from conversations 67 and 66.
