feat: add skill tags and tech stack section to DevCard profile

[Nareshkumawat-star]

Feature Request

DevCard is targeted at developers but has no way to showcase skills or tech stack. Adding a tags section would make it far more useful at hackathons and networking events.

Proposed Solution

• Add a "Skills" section to the profile with searchable tag input
• Pre-populated suggestions: React, Python, TypeScript, AWS, Flutter, etc.
• Tags displayed as styled chips on the DevCard
• Max 10 tags per profile
• Backend: store as string[] on the user profile model

Affected Platforms

• Web
• Mobile
• Backend
