feat: add Phase 2 migration, make urls command, fix seed script

- Create loyalty_003 migration: company-based architecture (adds
  company_id to all loyalty tables, creates company_loyalty_settings,
  renames vendor_id to enrolled_at_vendor_id on cards)
- Move platform migration back to alembic/versions (not loyalty-specific)
- Add version_locations to alembic.ini for module migration discovery
- Add make urls/urls-dev/urls-prod commands (scripts/show_urls.py)
- Fix seed_demo.py: import all module models to resolve SQLAlchemy
  string relationships, fix multiple admin query, set platform_id
  on vendor content pages
- Fix loyalty test fixtures to match Phase 2 model columns
