feat: implement Phase 2 - Alembic migrations, Pydantic schemas, and real API endpoints

- Add initial Alembic migration with full PostgreSQL schema (enums, tables, indexes, constraints)
- Add seed data migration with basic ingredients (70+) and family profile
- Add Pydantic schemas for all models (FamilyProfile, Recipe, MealPlan, etc.)
- Implement /api/profile endpoints (CRUD, family member management)
- Implement /api/recipes endpoints (CRUD, ingredients, filtering)
- Implement /api/meals endpoints (meal plans, voting, approval tokens)
- Implement /api/pantry endpoints (CRUD for home pantry)
- Implement /api/shopping-list endpoints (aggregation, print-ready HTML)
- Implement /api/admin endpoints (scrape trigger, logs, stats)
- Update ORIENTATION.md with Phase 2 progress
