feat: implement comprehensive recipe management schema

Browse Source 
- Add full database schema with accounts, dishes, ingredients, categories, and pricing
- Implement custom types for weight, currency, recipe difficulty, and color hex
- Add soft delete pattern with deleted_at and active views for all tables
- Include journaling triggers for created_at/updated_at automation

feat: add SQLC configuration with proper type overrides
- Configure SQLC to use UUID, decimal, and timestamptz types with proper Go mappings
- Add github.com/shopspring/decimal dependency for precise decimal handling
- Set up proper pointer handling for nullable fields in generated structs

refactor: replace simple food_items with full dish management system
- Remove old FoodItem model and replace with comprehensive Dish model
- Implement dish creation and retrieval queries with full field support
- Add ingredient management with weight/amount tracking

chore: update infrastructure dependencies
- Switch to custom PostgreSQL image with pg_idkit extension for UUIDv7 support
- Add DATABASE_URI environment variable configuration
- Update Docker Compose configuration for new database image

chore: organize SQL with fold markers and section comments
- Add vim fold markers for better code navigation
- Structure schema into clear sections: extensions, types, tables, triggers
- Separate query files with organized comment blocks
