Move entity storage to the Orchestration

[wcalderipe]

This PR introduces several changes to move the entity storage from the authz to the orchestration application.

Disclaimer

• The massive PR felt right to delivery an end-to-end solution; nonetheless, my bad.
• I have aggressively moved things from one place to another without thinking too much about how they're designed.

Changelog (at least what matters)

• Moved entity management from the authz to the orchestration application.
• Changed many DTOs to improve Swagger documentation.
• Replaced mock data by known personas and prefixed addresses.
• Configured @nestjs/swagger/plugin to automatically annotate DTOs.

Next

• Verify permissions to manage entities
• Remove SQLite persistence in the authz (see Refactor domain, entity, and action shared types #113)
• Move remaining entity types from action.type.ts to entity.type.ts (see Refactor domain, entity, and action shared types #113)
