Refactor: migrate units index state from AngularJS to Angular

[JeffySam]

Summary

This PR performs a strict migration of the Units Index state from AngularJS (CoffeeScript) to Angular.

The legacy AngularJS state and template have been fully removed and replaced with an Angular component and Angular-managed UI-Router state.

Changes

• Removed legacy CoffeeScript state and template:

  • index.coffee
  • index.tpl.html

• Added Angular replacements:

  • index.component.ts
  • index.component.html
  • index.component.scss
  • index.state.ts
  • Updated projects/states/index/index.coffee to remove dependency on deleted units/states/index/index.tpl.html (compatibility fix).
  • src/app/projects/states/index/index.coffee was updated only to remove templateUrl: "units/states/index/index.tpl.html" because that template is deleted as part of strict migration.

• No CoffeeScript remains for units/index state.

• Registered the new Angular state in doubtfire.states.ts

• Updated dependent AngularJS state to delegate rendering to Angular

• Added a minimal AngularJS shim module (index.ajs.module.ts) to preserve module dependency resolution (no logic, no state)

Migration Notes

• This is a strict migration (no hybrid controller or template usage)
• AngularJS is no longer responsible for routing or rendering this feature
• The shim module exists solely to prevent AngularJS module resolution errors
• Application boots successfully, login works, and unit pages load correctly

Testing

• npm start
• Verified login flow
• Navigated to unit pages (/units/:unitId)
• Confirmed Angular component renders and routing functions as expected
