Add performance bands API support

[faithque]

Description

This pull request completely overhauls the "Performance Bands" component on the progress dashboard by migrating it from static mock HTML into a robust, standalone Angular directive.

Previously, the performance bands defaulted to an empty 0% state for students without rigidly graded tasks. This PR implements a dynamic trajectory calculation based on the student's live $scope.project.activeTasks(). The system now successfully groups task statuses and evaluation criteria into four bands (High Distinction, Above Average, Average, Below Average), guaranteeing a continuous representation of progress throughout the term.

Additionally, this change replaces the previous flat CSS layout with a premium, sleek aesthetic featuring physics-like micro-animations, color gradients, and elevation styling.

The change includes:

• Updating performance-bands.coffee logic to dynamically map live task progression instead of static percentage properties.
• Refactoring performance-bands.tpl.html and performance-bands.scss into a premium responsive component with native data bindings.
• Extracting the static HTML card from progress-dashboard.tpl.html and replacing it with the dynamic <performance-bands> directive tag.
• Updating doubtfire-angularjs.module.ts to actively import the isolated component into the modern Angular bundler pipeline.
• Dropping obsolete state variables from the progress-dashboard.coffee controller.
