Mark Reviewed

Set or clear the human-reviewed flag on a quote.

Pass {"reviewed": true} (or omit the body) to mark as reviewed. Pass {"reviewed": false} to clear the review, allowing further edits before re-reviewing and sending.

Marking reviewed is rejected with 422 until the quote is actually ready: it must have at least one delivery option generated AND every part in the project must be priced. The un-review path is not gated by these prerequisites.

Un-reviewing is blocked once the quote has been sent to the customer.
