Unit ask-messages

Partially superseded by notifications-rework-plan.md: Ask dialog only - no duplicate "needs a decision" OS toast when the dialog is shown. If Asks paused -> one reminder max, not a storm. IP copy stays plain (no Agents-only jargon).

Still relevant

• Plainer Ask dialog copy
• Pause / resume -> Settings -> Advanced
• IP blocked messaging for messengers without jargon
