Chore/angular v19 migration

[mayhmemo]

Description

Angular v20 is now officially released and in production. To prepare for a full upgrade, i first updated the project from Angular v18 to v19. This intermediate step allows for proper validation of all functionalities before completing the final upgrade to v20 in a separate branch.

I followed the first part of the official Angular upgrade guide: Angular Update Guide (v18 to v20).

During this upgrade, i addressed the deprecation of HttpClientModule by replacing it with the new provideHttpClient() function, as recommended in the Angular documentation: HttpClientModule API Reference.

Additionally, i encountered an issue with the Tauri build. Although the build process completed successfully, running the app resulted in the error: "Asset 'index.html' not found". Upon investigation, i discovered that Angular now outputs build artifacts to /dist/browser instead of just /dist. Updating the distDir path in tauri.conf.json resolved the issue.

I also made some changes to the workflows build process, updating the dependencies.
