Investigate config module dependencies and clean up legacy root-controller usage

[sheshankarvapally]

Summary:

This PR continues Task 2 by migrating the legacy AngularJS config dependency area away from CoffeeScript as part of the Angular 17 migration effort.

Changes made:

• Removed config.coffee

• Removed root-controller.coffee because AppCtrl had no functional logic

• Removed routing.coffee

• Removed runtime.coffee

• Removed dependency on the old doubtfire.config module

• Updated index.html to remove AppCtrl usage

• Kept required config submodules such as:

  • doubtfire.config.vendor-dependencies
  • doubtfire.config.analytics
  • doubtfire.config.debug
  • doubtfire.config.privacy-policy

Investigation Findings:

• The removed config layer was acting mostly as a legacy wrapper
• AppCtrl/root-controller had no active business logic
• The AngularJS config dependency could be simplified safely
• Legacy CoffeeScript configuration files can now be migrated cleanly

Testing:

• Confirmed AppCtrl references are removed
• Confirmed old doubtfire.config dependency is removed
• Confirmed Angular bundle generation completes successfully
• Verified application loads after migration cleanup
• Backend/API issues observed were local Docker setup issues and unrelated to this migration

Hi @sheshankarvapally,
Reviewed and tested locally.
The application loads correctly, navigation works as expected, and no console/runtime errors were encountered during testing.
The migration cleanup and legacy CoffeeScript dependency removal align with the task objectives. Looks good to me.
