feat: angular migration v19

[matthieu-crouzet]

I don't know how you handle the releasing of this project.
I did the migration to Angular v19 and new APIs like (inject, input-signal, output, control flows). I splitted it in several commit in case you don't want all of them.
For the input-signal 3 inputs has not been migrated (flagged with TODO) because their values are modified in the component, we may think to use model instead.

Thank you, and yes, Angular 19 already – time flies! I’ve sent you an invite to become a maintainer. Feel free to merge into develop whenever you want. I’ll let you finish the version upgrade.

Hello @RawZ06,
I think this PR is ready to be merged, but I don't how you handle the releasing of a new major.
So I will let you merge that PR if you are okay with it and deploy a new major version of that package.
Thank you ! 😄

Thanks a lot! I won’t merge it for now—I’ll take the time to study it on my end. I haven’t had the time lately, but I’ll do it as soon as possible.

I would like to congratulate you on the work; it’s very, very clean. You have adhered to the standards with Angular signals—it’s an excellent job. Thank you so much for the time you dedicated to it. Thanks also to @fpaul-1A for the reviews. Well done, I’m merging!
