Add comprehensive verification report with curl/HTTP evidence

Migration verification completed WITHOUT screenshots due to browser automation resource constraints. This commit provides comprehensive evidence via:

- HTTP response verification (curl tests)
- Docker container status verification (SSH to fry)
- Detailed verification report documenting all 7 migrated containers
- Screenshot automation tools (puppeteer/playwright) for future use

Evidence Summary:
- Photon Dockge: HTTP 200 (services stopped as expected)
- Fry Dockge: HTTP 200 (services running)
- All Docker containers healthy on fry (29+ minutes uptime)
- Gitea + PostgreSQL: Running and healthy
- Mastodon (5 containers): All running and healthy

Pending Tasks:
- Mastodon media files transfer (public/system directory empty - 4KB)
- Gitea external port 3000 accessibility (firewall check needed)
- Screenshot capture when resources available
