- Replace plain text inputs with SymbolAutocomplete (existing component)
in both CorridorPanel and ConfluencePanel
- Add explanatory text to both panels describing what the visualization
shows and how to interpret results
- Fix symbol reset bug: panels now sync with global activeSymbol store
so symbol persists across tab switches and page reloads
- Add 'Run evaluation now' button when no corridor snapshot exists,
wired to existing runEvaluationNow mutation
ConfluencePanel shows the current picture quality for a symbol+rack, a
color-coded evidence summary, a per-slot fired/not-fired evidence grid with
notes, and the reliability scorecard. Uses the existing LayoutShell and
CollapsibleSection patterns. ADR-0007: quality labels are evidence-based
descriptions, never buy/sell directives.
