Migrate/root controller

[Thirus224849242]

Description

This PR migrates the root-controller from CoffeeScript and AngularJS to TypeScript and Angular as part of the ongoing Doubtfire migration effort.

The original AppCtrl controller was empty with only a GlobalStateService injection and no implementation. The new RootControllerComponent maintains this behaviour while following the Angular component pattern.

Changes made:

• Created root-controller.component.ts as the Angular replacement for root-controller.coffee
• Registered RootControllerComponent in doubtfire-angular.module.ts declarations
• Downgraded RootControllerComponent in doubtfire-angularjs.module.ts using downgradeComponent to maintain hybrid app compatibility
• Registered AppCtrl controller in doubtfire-angularjs.module.ts to maintain compatibility with ng-controller="AppCtrl" in index.html
• Removed doubtfire.config.root-controller from config.coffee
• Deleted old root-controller.coffee

Fixes # (issue)

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

The app was loaded and tested locally after each change to ensure nothing broke. The ng-controller="AppCtrl" in index.html continues to work correctly via the downgradeComponent bridge.

Hi @Thirus224849242 ,
Reviewed locally and tested successfully. The migration keeps the original AppCtrl behaviour, replaces the old CoffeeScript/AngularJS root controller with the new TypeScript/Angular component, and maintains hybrid app compatibility through the downgrade bridge. No issues from my side. Approved.

Tested locally and the application runs without issues:
Verified that the new Tasks.Component integrates correctly within the hybrid Angular/AngularJS setup. The downgradeComponent configuration appears correct, and no dependency or injection errors were observed after removing the doubtfire.tasks module reference.
Confirmed that existing task-related functionality (including project-tasks-list.coffee and modals.coffee) continues to work as expected, indicating that child AngularJS modules are still loading independently.
The migration aligns with the intended approach of incrementally replacing AngularJS modules without introducing additional logic.
