Pull request overview

This PR implements Story 3.2: Update Monthly Budget, allowing company owners to modify existing monthly budgets. The implementation follows a hexagonal architecture pattern with clear separation between domain, application, and infrastructure layers across both backend (Java/Quarkus) and frontend (TypeScript/React).

Changes:

• Added backend use case for updating budgets with owner authorization and audit logging
• Created frontend edit form with warning dialog for budget reductions
• Fixed JPA repository to handle both insert and update operations
• Included comprehensive unit tests (5 test cases)
