Update CI permissions and improve pull request handling

[omatheusmesmo]

This pull request introduces several improvements and refactorings across the frontend and backend documentation, focusing on user experience enhancements, code cleanup, and the addition of new dialog components for managing list items. The most notable changes are the implementation of dialog-based item management, removal of unnecessary logging for cleaner code, and updates to the workflow configuration for better CI/CD security.

Frontend Feature Additions

• Added ListItemDialogComponent for adding and editing items in a list, including its template and styles (list-item-dialog.component.ts, list-item-dialog.component.html, list-item-dialog.component.scss). The dialogs are now used in ListDetailsComponent for both add and edit actions, improving user interaction and code modularity. [1] [2] [3] [4]
• Updated ItemsManagementComponent to use a dialog for adding items, replacing placeholder code with a full implementation for better UX.

Codebase Cleanup and Error Handling

• Removed console logging and improved error handling in UnitsManagementComponent, ItemsManagementComponent, ListDetailsComponent, and auth.interceptor.ts, resulting in cleaner production code and more consistent user feedback via snack bars. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]

Workflow and Documentation Improvements

• Changed GitHub workflow triggers from pull_request to pull_request_target for improved security and correct event handling, and updated conditional logic to match the new event type. [1] [2] [3]
• Enhanced the README.md with clearer environment setup instructions, Docker usage, and manual run steps, making onboarding easier for new developers.

Other Refactorings

• Minor RxJS and import cleanups in ListDetailsComponent for improved code clarity. [1] [2]

These changes collectively improve the maintainability, security, and user experience of the application.
