test(resumeprofilesection): add type compiler validation coverage (JhaSourav07#3249)

## Description

Fixes JhaSourav07#2712

This PR adds the new test file:

`components/dashboard/ResumeProfileSection.type-compiler.test.tsx`

The new test suite validates TypeScript compiler behavior and prop type
safety for `ResumeProfileSection.tsx`.

It includes type assertions for:

* required prop enforcement
* strict prop validation
* undefined rejection
* compile-safe prop structure validation
* valid string prop acceptance

using `expectTypeOf`.

## Pillar

* [x] 🛠️ Other (Bug fix, refactoring, docs)

## Visual Preview

N/A (type compiler test coverage update)
