feat: add content ID and enabled status to shop content responses

Changes:
- Added 'id' field to content items in GET /api/shops/:id response
- Added 'id' field to content items in GET /api/shops/:id/results response
- Added 'enabled' field to both endpoints showing URL enable/disable status

This allows the frontend to properly manage content URLs using the
PATCH /api/shops/:id/content/:contentId endpoint for enabling/disabling URLs.
