Upgrade Angular to v19 using the update guide.
- Add `standalone: false` to any missed component in stories or tests.
- Update jest.config to follow the new best practices.
Fail tests when relying on unknownProperties or unknownElements. Existing instances are whitelist and have tickets created and assigned to the relevant teams.
Extract core functionality from `libs/angular` to allow teams to depend on `libs/ui-common` instead.
Moves the following functionality to `ui-common`.
- `I18nPipe`. `libs/angular` still has an old copy but `components` depends on the new variant from `ui-common`.
- `safeProvider`, `SafeProvider` and `SafeInjectionToken`. `libs/angular`re-exports these to avoid needing to update all consumers.
