feat: Setup zero-downtime deployments for production and dev branches

- Created separate workflows for production and dev deployments
- Production branch → dk0.dev (port 3000)
- Dev branch → dev.dk0.dev (port 3002)
- Zero-downtime deployment pattern (start new, wait for health, remove old)
- Complete isolation between environments (separate containers, databases, networks)
- Cleaned up unused code and files:
  - Removed unused GhostEditor and ResizableGhostEditor components
  - Removed old/unused workflows and markdown files
  - Fixed docker-compose references
- Upgraded dependencies to latest compatible versions
- Fixed TypeScript errors in editor page
- Updated staging to use dev.dk0.dev domain
