[Feature]: AI optimization for all resume modules

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

Currently, the AI generation feature is only available for a limited set of modules. Many important sections cannot be improved with AI.

Describe the solution you'd like

Enable AI optimization (rewriting, grammar fixing, tone improvement, keyword enhancement) for all resume modules, including but not limited to:

• Skills
• Certifications
• Professional Summary / Self-introduction (plain text)
• Languages
• Projects (if not already covered)
• Awards
• Volunteer experience
• Custom modules

Describe alternatives you've considered

sorry.

Additional context

Expected Behavior

Each editable field should have an "AI Optimize" button (similar to existing ones). When clicked, the AI suggests improvements to the content based on best practices and job description matching (if available).

Expected Benefit

Users can maintain consistent quality across the entire resume.

Reduces manual effort for rewriting each section.

Makes the tool more valuable for job seekers.
