**Motivations :**
* Allow associating administrative procedures to module components with status tracking
* Centralize regulation characteristics configuration for better data consistency
* Link regulation characteristics to wastes, regulators, ecosystems, and module components
**Root causes :**
* Need to track administrative procedures per module component
* Regulation characteristics were hardcoded in multiple places, causing inconsistency
* No centralized way to manage and reference regulation characteristics
**Correctifs :**
* Added ModuleComponentProcedureAssociation interface with procedureId, status, and notes
* Created RegulationCharacteristic entity with name, code, category, description, unit, isBoolean, minValue, maxValue
* Added regulationCharacteristicIds field to Waste, NaturalRegulator, Ecosystem, and ModuleComponent
* Updated all configuration pages to use regulation characteristics from centralized configuration
* Created RegulationCharacteristicsConfigurationPage for managing characteristics
* Added seeds for regulation characteristics (31 characteristics covering all categories)
* Added seeds for companies (4NK Water & Waste default company)
**Evolutions :**
* Module components can now have associated administrative procedures with status (toDo, done, na)
* Regulation characteristics are now centralized and can be referenced by multiple entities
* All regulation needs and characteristics are now managed through a single configuration page
* Business plans can be added to all entities (already implemented, documented in data_schemas.md)
* Updated data_schemas.md with complete documentation of all entities, relations, and validation rules
