epic(refactor): Heureka Refactoring

[lolaapenna]

Initially, Heureka's scope was solely focused on the management of vulnerabilities. However, in our pursuit of comprehensive security management, we have broadened our scope to include SIEM, policy violations, and other potential security threats.

Due to this expanded scope, we are in the process of implementing additions and modifications to our entity framework. These changes are expected to have implications on the following elements:

• The Entity Relationship Diagram (relationships remain unchanged)
• The Technical Documentation
• Backend Implementations

• feat(refactor): Update the Entity Relationship Diagram #29
• feat(refactor): Update the Technical Design Documentation #30
• feat(refactor): Modify Backend Implementations #31
