Supabase persistence for Slack signals

1. In Supabase SQL editor, run backend/supabase_signals.sql.
2. Set backend env vars:

$env:SUPABASE_URL="https://<project-ref>.supabase.co"
$env:SUPABASE_SERVICE_ROLE_KEY="<service-role-key>"
$env:SUPABASE_SIGNALS_TABLE="signals"  # optional, default is signals

3. Start backend from backend/.

When these env vars are set, Slack-imported signals are upserted into Supabase and /api/signals reads from Supabase.

Security note: use only the service-role key on backend server side. Never expose it in frontend code.
