feat(platform): add Agent Output Demo field to marketplace submission form (#11538)

## Summary
- Add Agent Output Demo field to marketplace agent submission form,
positioned below the Description field
- Store agent output demo URLs in database for future CoPilot
integration
- Implement proper video/image ordering on marketplace pages
- Add shared YouTube URL validation utility to eliminate code
duplication

## Changes Made

### Frontend
- **Agent submission form**: Added Agent Output Demo field with YouTube
URL validation
- **Edit agent form**: Added Agent Output Demo field for existing
submissions
- **Marketplace display**: Implemented proper video/image ordering:
  1. YouTube/Overview video (if exists)
  2. First image (hero)
  3. Agent Output Demo (if exists) 
  4. Additional images
- **Shared utilities**: Created `validateYouTubeUrl` function in
`src/lib/utils.ts`

### Backend
- **Database schema**: Added `agentOutputDemoUrl` field to
`StoreListingVersion` model
- **Database views**: Updated `StoreAgent` view to include
`agent_output_demo` field
- **API models**: Added `agent_output_demo_url` to submission requests
and `agent_output_demo` to responses
- **Database migration**: Added migration to create new column and
update view
- **Test files**: Updated all test files to include the new required
field

## Test Plan
- [x] Frontend form validation works correctly for YouTube URLs
- [x] Database migration applies successfully 
- [x] Backend API accepts and returns the new field
- [x] Marketplace displays videos in correct order
- [x] Both frontend and backend formatting/linting pass
- [x] All test files include required field to prevent failures
