Add provideFingerprint() for standalone Angular apps and Angular 21 demo

[ilfa]

Summary

• Adds provideFingerprint() — a new EnvironmentProviders-based function for configuring Fingerprint in standalone Angular applications (Angular 14+) via bootstrapApplication / ApplicationConfig
• FingerprintModule.forRoot() remains fully supported for NgModule-based apps (backward compatible)
• Adds demo-angular21 — a demo application built with Angular 21, showcasing modern Angular patterns: standalone components, inject(), signals, and new control flow syntax (@if)
• Fixes dual Angular instance issue in the monorepo caused by pnpm resolving @angular/core to two different store entries

It seems package.json required Angular 15+ ?

That's right, I also added a link to the Angular docs

Pull request overview

This PR adds first-class standalone-app configuration support for the Fingerprint Angular SDK via a new provideFingerprint() API, and introduces a new Angular 21 demo app to showcase modern Angular patterns alongside the existing NgModule-based demo.

Changes:

• Added provideFingerprint(settings) (EnvironmentProviders) and exported it from the library public API, with Jest unit tests.
• Updated demo config naming (fingerprintPublicKey) and test TS configs to include Node types.
• Added a new projects/demo-angular21 standalone Angular 21 demo app and adjusted workspace/pnpm settings for the monorepo.

Minor Changes

• Add provideFingerprint function for standalone Angular applications (Angular 15+).

  This allows configuring the SDK without NgModule in bootstrapApplication or ApplicationConfig:

  import { provideFingerprint } from '@fingerprint/angular'
  
  export const appConfig: ApplicationConfig = {
    providers: [provideFingerprint({ startOptions: { apiKey: 'your-api-key' } })],
  }

  FingerprintModule.forRoot() remains available for NgModule-based applications. (fbf3eb8)
