Is your feature request related to a problem? Please describe.

This files in this directory and all its subdirectories are currently tested using Jest. As part of our migration to Vitest, we need to refactor all these files' test cases to align with Vitest's syntax and features.

Files:

1. Refactor src/components/UserProfileSettings/DeleteUser.test.tsx from Jest to Vitest
2. Refactor src/components/UserProfileSettings/OtherSettings.test.tsx from Jest to Vitest
3. Refactor src/components/UserProfileSettings/UserProfile.test.tsx from Jest to Vitest

Acceptance Criteria

For each *.test.ts and *.test.tsx file found under the parent:

1. Replace Jest-specific functions and mocks with Vitest equivalents
2. Rename the test file from having a .test.* suffix to a .spec.* suffix
3. Ensure all tests in the file pass after migration using npm run test:vitest
4. Maintain the test coverage for the file as 100% after migration
5. Upload a video or photo for this specific file coverage is 100% in the PR description
