chore: fix skipped test cases in frontend app support tools

[Akanshu-2u]

Description
Certain test cases were failing in frontend-app-support-tools due to the migration from Enzyme to React Testing Library (RTL). The existing functions and utilities were not properly adapted to work with RTL and were more suited for Enzyme. Therefore, I made the necessary changes to align them with the new testing library.

ProgramInspector.test.jsx

  1. Unskipped the test: Removed it.skip from "check if SSO is present" test
  2. Fixed mock persistence: Changed mockImplementationOnce to mockImplementation in beforeEach for all mocks to work across multiple API calls
  3. Used consistent query approach: Kept document.querySelector instead of RTL role queries since input elements lacked proper id attributes for accessibility
  4. Corrected test expectations: Changed from expecting "tpa-saml (Provider)" to expecting "SSO Record Not Found" to match actual test data
  5. Proper mock setup: Set up the getProgramEnrollmentsInspector mock before rendering in the failing test

CourseEnrollment.test.jsx

1. Migrated from Enzyme to React Testing Library (RTL):

    - Replaced Enzyme's mount(), find(), simulate() with RTL's render(), screen.getByText(), fireEvent()
    - Updated test selectors to use screen queries and document.querySelector()

2. Fixed Form Event Handling:

    - Changed from simulate('change') to fireEvent.change() with proper target values
    - Updated select field values to match actual options (e.g., 'other' instead of 'Other')

3. Added Proper Async Handling:

   - Used waitFor() for asynchronous operations
   - Added act() wrapper for form submissions
   - Ensured form state updates before assertions

4. Fixed Test Assertions:

  - Updated button presence checks to use toHaveAttribute('hidden') instead of not.toBeInTheDocument() since hidden buttons are still in DOM
  - Fixed error message assertions to use RTL queries

5. Added Missing Import:

 - Added import * as api from '../data/api' for API mocking

Entitlements.test.jsx

  - Removed .skip: Unskipped all previously skipped tests
  - Fixed dropdown interactions: Used act() wrapper for dropdown clicks to handle state updates
  - Fixed async operations: Added proper waitFor() for UI state changes
  - Fixed test data: Used correct test data and assertions
  - Fixed API mocking: Proper setup of entitlements and course data API mocks

CourseReset.test.jsx

  - Removed .skip: Unskipped all previously skipped tests
  - Fixed async/await: Added proper act() and waitFor() for async operations
  - Fixed user interactions: Used proper fireEvent and userEvent for button clicks
  - Fixed timer tests: Added jest.useFakeTimers() for polling functionality tests
  - Fixed API mocking: Proper setup of getLearnerCourseResetList and postCourseReset mocks

CourseSummary.test.jsx

  - Fixed API mocking: Added proper jest.spyOn(api, 'getCourseData') mocks for each test
  - Fixed mock cleanup: Added proper beforeEach and afterEach to reset mocks
  - Fixed test structure: Ensured each test has its own API mock setup
  - Fixed error test: The "Course Summary Fetch Errors" test was expecting the correct title behavior when errors occur
