fix: comment out D1 binding until database is created

The D1 AUTH_DB binding causes deploy failure when the database
doesn't exist yet. Code already handles AUTH_DB being undefined
(falls back to legacy token auth). Uncomment after running:
  wrangler d1 create md-auth
  wrangler d1 execute AUTH_DB --file=schema.sql
