fix: resolve major CLI design principle violations

HIGH PRIORITY FIXES:
- Remove deployment.py entirely (653 lines) - was complete DevOps platform in CLI
- Fix browser opening - Provide URL instead of auto-opening browser
- Replace blocking loops - Use single status checks instead of infinite loops
- Simplify KYC/AML - Use basic HTTP calls instead of async clients

DESIGN PRINCIPLES RESTORED:
- CLI controls, doesn't run services
- CLI provides information, doesn't block indefinitely
- CLI is lightweight, not a deployment platform
- CLI respects user control (no auto-opening browsers)
- CLI uses simple HTTP clients, not connection pools

REMOVED:
- aitbc_cli/core/deployment.py (653 lines of DevOps code)
- webbrowser.open() auto-opening
- while True: blocking loops
- aiohttp async connection pools
- Complex deployment management

SIMPLIFIED:
- KYC/AML providers now use basic HTTP calls
- Agent status provides single check with guidance
- Explorer provides URL instead of auto-opening
