Self-host RICO TRADING with a local dashboard

Self-hosting is now documented end to end. The self-host quickstart script spins up Postgres, applies the schema, seeds a demo account (LOCAL-SIM-001), and writes a .env.local you can use right away. SELF_HOSTING.md and AGENTS.md walk through Docker, env vars, and what to expect when you run the stack on your machine.

With local dashboard auth bypass enabled, /dashboard loads without Supabase login and /authentication redirects you there instead. Trade import and save work in this mode, so you can exercise the full journal workflow offline or in a private deployment.

Bypass mode is meant for local development and self-hosted setups, not production SaaS. Production refuses to start with bypass unless you explicitly opt in via the documented override.
