Angular 21 Compatibility

• refactor(sidebar.service): cleanup
• refactor(dropdown.service): cleanup
• refactor(sidebar-nav): signal inputs, test
• refactor(sidebar-nav.service): SidebarNavHelper providedIn: 'root'
• refactor: migration from NgClass to class bindings
• refactor: migration from NgStyle to style bindings
• test: RouterTestingModule migration, updates, cleanups and fixes

Fixes

• fix(multi-select): use signal selectedOptions to avoid NG0100 for zoneless
• fix(time-picker): use signal queries to avoid NG0100 - expression changed after checked for zoneless
• fix(autocomplete): delay prop not working - thanks to @bernik1980 for reporting and helping resolve issue #239.
• fix(dropdown): potential infinite loop setting listeners
• fix(form-password): c-form-feedback not displayed - thanks to @bernik1980 for reporting and helping resolve issue #237.
• fix(one-time-password): c-form-feedback not displayed

Refactors

• refactor(multi-select-optgroup): signal inputs, queries, host bindings, cleanup
• refactor(autocomplete): dropdownMenu show cleanup

Migration Notes

To keep your application lean and compliant with Angular 21, we recommend the following actions:

• Cleanup Providers: Remove importProvidersFrom(SidebarModule, DropdownModule) from your bootstrapApplication calls. These services now use providedIn: 'root'.
• Zone Management:
  • Zoneless: Test your app functionality to ensure everything remains reactive.
  • Zone-based: Add provideZoneChangeDetection() to your root providers if not already handled by automated migration.
• Interpolation: Remove the interpolation property from @Component decorators; Angular now only uses the default {{ and }} interpolation markers.
