fix: make Analysis tab robust when no snapshot data exists

Browse source 
- showView() now tracks _curView, scrolls to top, forces visibility
- loadAnalysis() shows clear "No data yet" message when API returns null
  instead of silently leaving static placeholder text
- forceRefreshAnalysis() added: POSTs /api/refresh then reloads analysis
- ↻ Refresh button added at top of Analysis view with live timestamp
- Auto-refresh analysis every 30s when Analysis tab is active
