Implement helper packages for fluent database factories

[komed3]

Develop specialized helper packages to simplify database interaction and improve the data entry process.

Key Components:

• H&P Phrases: A dedicated package for managing Hazard (H) and Precautionary (P) statements, ensuring safety data is handled consistently.
• Fluent Database Factories: Instead of writing raw JSON or deep TypeScript objects manually, implement a factory system using a Fluent Design pattern.

Objectives:

• Reduce human error during data definition.
• Make the schema more accessible for contributors.
• Provide a more intuitive, functional API for building database entities.
