Link Personalization (User-Specific Links)

[danilovid]

Description

Associate links with users so each user sees only their own links. This requires updating the link creation flow to include user context.

Requirements

• Update link creation to require authenticated user
• Filter links by user_id in all queries
• Update API endpoints to use user context from JWT
• Migrate existing links (optional: assign to default user or keep global)

Technical Details

• Database: link_models table already has user_id column (from migration 002)
• Backend:
  • Update LinkCreateInput to include user_id from context
  • Add user_id filter to all repository queries
  • Update API handlers to extract user from JWT token
• Frontend: Ensure user context is passed with all requests

Acceptance Criteria

• Links are associated with users
• All link queries filter by user_id
• API endpoints use JWT user context
• Frontend sends auth token with requests
• Migration script for existing data (if needed)
• Tests updated for user-specific links
