Revamp Demo and Minor fixes

[18.5.0] — 2026-06-03

Fixed

• Scoped NguiAutoCompleteService per-component instance (was a module singleton — multiple simultaneous
  <ngui-auto-complete> components overwrote each other's source property causing a runtime crash)
• isLoading no longer stays stuck true after a failed HTTP request — error handler now resets it
• ngOnDestroy subscription teardown: replaced invalid EventEmitter.unsubscribe() calls with proper
  RxJS Subscription management via dropdownSubs
• Replaced UntypedFormControl / UntypedFormGroup with typed FormControl / FormGroup
• Root .eslintrc.json referenced non-existent e2e/tsconfig.json — removed
• Project ESLint configs used file-relative tsconfig paths — changed to workspace-root-relative
• demo:prefix in angular.json was docs instead of app
• Removed broken ct Cypress component-test target from the library angular.json entry
  (referenced non-existent auto-complete:serve target)
• auto-select-first-item demo was missing [auto-select-first-item]="true" — feature was never active

Changed

• Replaced deprecated karma-coverage-istanbul-reporter with karma-coverage
• Removed unused @types/jasminewd2 (Protractor artefact, not needed with Cypress)
• Pinned cypress to ^13.0.0 instead of "latest"
• Demo Observable source example replaced from Marvel API (broken auth) to Open Library (free, no key)
• Demo HTTP source examples replaced from Google Maps (requires key) to Nominatim/OpenStreetMap (free, no key)
• RTL demo updated to use Arabic city names with dir="rtl" scoped to the demo area only

Added

• Angular Material toolbar in demo app with library title and links to GitHub / npm
• Demo examples use <mat-card> layout in a responsive CSS grid (2-column desktop, 1-column mobile)
• Collapsible "View Template" expansion panel per demo example
• MatToolbarModule, MatCardModule, MatExpansionModule, MatButtonModule added to demo module
• Revamped styles.scss: indigo-pink Material theme, global typography, dark code-block styling
• Descriptive subtitles and usage hints on all directive and component demo examples
• Restructured README: badges, API reference table, version-compatibility table, updated dev instructions
