Business Manager

### Problem
The client has requested the **permanent retirement** of the Business Manager project. The project must be **fully removed** from all systems, with no traces remaining in any environment or tool. This includes:

- **Complete shutdown** of all environments (development, staging, production).
- **Permanent deletion** of all data (user profiles, audit logs, financial records) with **no backup or recovery option**.
- **Removal from all tools** (Harbor, Pipeliner, Redmine, etc.) to ensure the project no longer appears in lists, dashboards, or reports.
- **No user communication**—closure will be handled internally without notice.

### Context
The Business Manager project is a secure financial management tool with the following key components:
- **Web App (Next.js)**: Handles user sign-in (Google OAuth) and displays data.
- **API (Go)**: Enforces security, manages data, and logs all actions (stateless, token-based).
- **Database (Postgres)**: Stores user profiles, audit logs, and financial data.
- **Security Model**: Access is restricted via Google OAuth, an email allowlist, and role-based permissions.

The project is currently deployed across multiple environments, and all data must be **irreversibly deleted** to comply with the client’s request.

### Proposed Behaviour
1. **Shut down all environments** (development, staging, production) and disable access to the application.
2. **Delete all data permanently** from the database, including:
- User profiles (name, email, role).
- Audit logs (login events, user provisioning).
- Financial records (if any exist).
3. **Remove the project from all tools** (Harbor, Pipeliner, Redmine, etc.) to ensure it no longer appears in any system.
4. **Verify no traces remain**—confirm the project is inaccessible and untraceable in all environments and tools.
5. **No user communication**—closure will be handled internally without notifying users.

## Acceptance criteria
['- [ ] All environments (development, staging, production) are shut down and inaccessible to users.', '- [ ] All data (user profiles, audit logs, financial records) is permanently deleted from the database with no backup or recovery option.', '- [ ] The project is removed from all tools (Harbor, Pipeliner, Redmine, etc.) and no longer appears in any lists, dashboards, or reports.', '- [ ] No traces of the project remain in any system (e.g., no residual files, logs, or configurations).', '- [ ] The API and web app are disabled, and no requests can be processed.', '- [ ] No user communication is sent regarding the closure.']

## Classification
- feature

## Complexity
- 8/10 — The complexity is high due to the irreversible nature of data deletion and the need to ensure complete removal across multiple environments and tools.
