chore: integrate local imgproxy sidecar and unify list components

- Added imgproxy service to docker-compose.dev.yml with URL mapping
- Implemented robust Base64 encoding for imgproxy source URLs
- Synchronized NEXT_PUBLIC_IMGPROXY_URL and NEXT_PUBLIC_BASE_URL
- Refactored About page to use existing marc-mintel.png asset
- Created shared IconList component and unified list styles project-wide
- Fixed vertical alignment issues in IconList items
- Updated dev script with aggressive port 3000 and lock file cleanup
