Refactor/ab#82357 update angular fix memory leak issues and other fixes

[unai-reliefapp]

Description

Fixed, among other minor issues:

• fix most of the memory issues for unsubscribed values(some subscriptions are added on root services and cannot be unsubscribed until the app is closed) including unsubscribe flag for all widget settings forms, add missing subscription tear down for some observables
• refactor many subscriptions within subscriptions to a single subscribe method in order to keep the code simple, effective and readable
• fix all timeout listeners missing proper clear functions
• fix required control label update from form wrapper when no label is set in the html
• fix proper message sent on notification create/update/delete(duplication of same message and success message was send even if request failed)
• fix correct role list fetch on list inside application and duplicate display message for add/delete role(duplication of same message and success message was send even if request failed)
• fix property updates for resource and resources type questions in form builder, including search and add record button and table display and table buttons for resources

@AntoineRelief Changes made set in the description and in the related ticket I think there is plenty to merge, next step I'll go to is to make an error handler service in order to avoid multiple error handlers everywhere, or missing ones, and keep a consistent error messaging logic across the app

@unai-reliefapp Nice Perhaps we should create separate branches ( even if they use the other ones ) so the PR is not becoming bigger
