fix(health): add Supabase keepalive ping to GET / health check

Browse source 
UptimeRobot pings GET / every 5 minutes. Previously static response
only kept Node process alive but let Supabase connection pool go cold.
Now executes a lightweight HEAD query (profiles, limit 1) to maintain
DB connection warmth. Always returns 200 with db status field for
observability.
