- Reset memory backend status to unresolved during fetches so stale capabilities are never treated as authoritative
- Gate MemoryView read-only and qmd warning states on resolved backend status and add an explicit checking state for qmd availability
- Update SettingsModal memory editor gating so writes remain enabled while backend status is still loading, then enforce resolved read-only state
- Expand dashboard tests for useMemoryBackendStatus, MemoryView, and SettingsModal to lock in loading, warning, and refresh behavior
