Implement soft delete architecture

Description:

Summary

Implements logical deletion (Soft Delete) for the Application entity to ensure data retention for audit trails while allowing users to manage their drafts.

Technical Changes

• Infrastructure:
  • Schema migration adding deletedAt timestamp and index to the Application entity.
  • Refactored Application and Project repositories to enforce deletedAt: null filtering on all read/update operations, ensuring data consistency across relations.
• Domain & Application:
  • Implemented deletion use case with strict constraints: ownership validation and state verification (preventing deletion of Applications already converted to Projects).
• Presentation:
  • Exposed DELETE /application/:uuid endpoints for both Web and Mobile clients.
• Documentation:
  • Updated OpenAPI specifications to reflect new endpoints and response schemas.
