feat(deps): upgrade Angular to v21

- Update @angular/* packages to v21.0.8
- Update @angular/material and @angular/cdk to v21.0.6
- Update @angular-eslint/* to v21.1.0
- Update @ngrx/* to v21.0.1
- Update TypeScript to 5.9.3
- Update ngx-markdown to v21 and marked to v17
- Update typia to v11 for TypeScript 5.9 support
- Update @types/node to v22, chart.js to v4.5.1

Breaking changes addressed:
- Replace deep imports with public API imports (idb, formly, ngrx)
- Update marked-options-factory for marked v17 API changes
- Add custom FormlySliderComponent (formly slider incompatible with Mat v21)
- Update ngx-markdown SANITIZE configuration
- Fix HostListener decorators with unused $event args
- Fix crypto.subtle type compatibility
- Add skipLibCheck for dependency type conflicts
- Update tsconfig module settings for Angular 21

Removed:
- @angular-builders/custom-webpack (unused)
