Migrate/util service

[sakethsram8888]

Description
Migrates the utilService module from CoffeeScript (AngularJS) to TypeScript (Angular 17).

The file utilService.coffee has been rewritten as utilService.ts, converting the AngularJS
module definition to TypeScript while preserving all existing filters (fromNow, titleize, humanize)
and the autoFillSync directive.

The import in doubtfire-angularjs.module.ts has been updated to reference the new TypeScript
file directly instead of the compiled JavaScript build output.

Type of change

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

How Has This Been Tested?
The application was tested locally at localhost:4200. The app loads correctly and login
functionality works as expected with the new TypeScript file in place of the old CoffeeScript file.

Reviewed and tested locally on the review/pr-491 branch.

Verified that the application builds and runs successfully with the migrated utilService.ts implementation. Login, dashboard loading, task list display, and general navigation work as expected with no visible UI issues or console errors during testing.

Changes appear clean and limited to the intended utilService migration scope.
