Initialization

internal/initialize owns application bootstrap orchestration. It implements biz.InitializationRepo, coordinates the explicit first-install workflow, and formats the compatible runtime configuration API.

The package depends on a narrow Backend interface. *data.Data implements that interface and remains responsible for opening, migrating, activating, reloading, and persisting database-backed runtime infrastructure.

The first-install order is:

1. data opens the candidate database.
2. The single root migration runner applies infrastructure, system, and payment schema steps.
3. initialize invokes system.SeedSystem for administrator, menu, API, department, policy, and module administration-surface records.
4. data persists configuration and activates the candidate clients.

Schema migration and business seed data are deliberately separate. Normal startup and configuration reload may run migrations, but only the explicit first-install endpoint runs seed data.
