real Supabase schema + data loaded; cleanup synthesized placeholder

Major changes:
- Drop synthesized base schema (supabase/synthesized/000_base_schema.sql) —
  real pg_dump from Supabase is now the source of truth
- Switch better-auth from better-auth/minimal to better-auth (full)
- Add localhost:9000 (MinIO) to next.config images allowlist
- Add .data/, bin/ to gitignore (local runtime artifacts)
- Ignore supabase/captured/ (regenerate from Supabase as needed)

DB state after dump:
- 65 real tables (vs 70 synthesized)
- 252 functions
- 5 brands: Tuxedo Corn, Indian River Direct + 3 test brands
- 3 admin users, 1 communication template, 7 brand features
