DashboardState.bars() short-circuits to [] unless a research_con is attached; the
embedded orchestrator passed one but the standalone dashboard_api.py never built
it, so production sparklines were permanently dead. The missing wire was purely
the entrypoint (DATABASE_URL already reaches the market schema) — now it opens
open_research_db("market") read-only and passes it, degrading to None (charts
show "no research db") if it can't connect. Verified live: bars() returns real
minute rows through the standalone reader.
