[Dependencies]: Update Angular 21

[RiinaKuu]

DS-651

• Updated Angular packages to latest available 21 packages
  • Automatic migration removed "lib": ["ES2021", "dom"] from base tsconfig.json
• Updated peer dependencies to require at least Angular 21
• Updated jest which required also:
  • Few new package installs to dev dependencies (jest-environment-jsdom, jsdom)
  • ESLint, TS, and Jest config changes
    • ESLint: Added jest globals for test files so that every .spec does not require explicit jest imports
    • TS: Created new file for resolving the jest globals
    • Jest: Change legacy preset to CommonJS preset
• New jest-preset-angular version required esbuild and since our CI image installs dependencies from Dockerfile from our package.json it had to be installed as dev dependency in the project as well
• Some additional clean-ups for TS configs
  • Removed deprecated baseUrl (no longer required for paths)
    • This change required some path fixes in sandbox (internal import paths between workspaces are not allowed anymore)
  • Removed deprecated downlevelIteration (no longer necessary when using "target": "ES2022")
  • Added "rootDir", so that Typescript does not have to infer it
  • In library config, added "include" array and updated "exclude" array, since library should not include all the same paths which are in the base tsconfig.json (which it extends)
• Removed Zone.js import from Storybook since it is now zoneless by default and caused console warnings

---

VR tests:

• There were failures due to Chromium typing race conditions and Chromium was dropping characters during synthetic typing
  • Playwright's keyboard.type did not satisfy the event logic of (at least) the Select component's autocomplete variant and it had to be fixed by manually dispatching the keydown/keyup event pair

Developer's checklist

• I wrote necessary unit tests
• I updated Storybook stories and documentation to reflect the latest changes
• I included visual regression tests for new UI design
• I tested my implementation with different browsers
• I checked accessibility according to Web Content Accessibility Guidelines 2.1
• Together with the reviewer I can confirm that the implementation supports the following screenreader and browser combinations (NVDA + Firefox, VoiceOver + Chrome)
