Check changes in Angular 19 and plan updates

[evilaliv3]

Proposal

This ticket is to track the activities related to checking changes in Angular 19.

It should be verified:

• If the globaleaks codebase should be updated in relation to usage of outdated functions.
• Verify possibilities of optimizations to be adopted on new code
• Verify which are the dependencies that still miss support for Angular 19

List of dependencies that might require to be updated to Angular 19:

• Support Angular 19 ng-bootstrap/ng-bootstrap#4779
• Update to Angular 19 flowjs/ngx-flow#123

sure, will check it out. angular releases a new version. At the moment there are no code breaking changes just overall improvements in signal concept. Remember flicker issue in images due to zone js that continuously check for changes. Now angular is moving from this to a signal based approach but some things introduced at the moment are experimental but will look at it in detail
