fix(dashboard): hide escalation notes on resolved/superseded decisions

- `escalated` filter now excludes decisions with status resolved or
  superseded — a lingering escalation_note on a closed decision no
  longer triggers the warning box or shows the amber note on the card
- Resolves D1 Vault backend appearing to re-surface an escalation alert

Also resolved ADR-001 decision (was made/open, now made/resolved);
overview blocking-decision count is now 0.
