Pull request overview

This PR refactors the task and process filter components to use modern Angular patterns, including migration from structural directives to built-in control flow syntax, replacing mat-action-list with mat-nav-list for better navigation semantics, and adopting Material Design 3 theming tokens.

Changes:

• Migrated from *ngIf/*ngFor structural directives to @if/@for` built-in control flow syntax
• Replaced mat-action-list with mat-nav-list and integrated Angular router for filter navigation
• Updated SCSS to use Material Design 3 tokens with fallbacks to legacy theme variables
• Removed ViewEncapsulation.None from component decorators
• Simplified tests to focus on router navigation behavior instead of CSS class manipulation
