/**
 * ConfirmForgetDialog — AWS-style confirmation for destructive memory actions.
 *
 * The user must type the persona name exactly to enable the confirm button.
 * This prevents accidental deletions while keeping the UX lightweight
 * (no password re-entry needed).
 *
 * Used for:
 *  - Forgetting a single memory
 *  - Forgetting ALL memories for a persona
 *
 * Safety: memories are deleted, the persona itself is NEVER deleted.
