Remove barrel exports (index.ts files) in favor of direct imports

[zalexa19]

Description

Our codebase currently uses barrel exports (index.ts files) throughout the project, particularly in /src/components/index.ts. While this pattern provides shorter import paths, it has several drawbacks:

• Circular dependency risks: Barrel exports can create circular dependency issues that are hard to debug
• Poor tree-shaking: Bundlers may include unused code, resulting in larger bundle sizes
• Reduced code clarity: It's harder to trace where components actually live
• Maintenance overhead: Need to manually maintain export lists
• IDE performance: Can slow down IntelliSense and auto-imports

Proposed Solution

Migrate from barrel exports to direct imports across the codebase.

Before:

// src/components/index.ts
export * from '../features/trainee-profile/profile/components/TraineeProfile';
export * from '../features/trainee-profile/education/EducationInfo';

// Usage
import { TraineeProfile, EducationInfo } from '@/components';

After:

// Direct imports
import { TraineeProfile } from '@/features/trainee-profile/profile/components/TraineeProfile';
import { EducationInfo } from '@/features/trainee-profile/education/EducationInfo';
