feat: add delete operations and envs update to managed CLI

Adds missing CRUD operations for managed agents CLI parity:

✅ New Commands Added:
- praisonai managed sessions delete <session_id> [--yes/-y]
- praisonai managed agents delete <agent_id> [--yes/-y]
- praisonai managed envs update <env_id> [--packages ...] [--networking ...]
- praisonai managed envs delete <env_id> [--yes/-y]

✅ Key Features:
- Confirmation prompts: All destructive operations ask for confirmation
- Skip flag: --yes/-y flag bypasses confirmation prompts
- Pattern consistency: Follows existing code patterns in managed.py
- Error handling: Proper exception handling and user feedback
- Comprehensive tests: Unit tests using typer.testing.CliRunner

📁 Files Modified:
- src/praisonai/praisonai/cli/commands/managed.py - Added 4 CLI commands
- src/praisonai/tests/unit/cli/test_managed_cli_destructive.py - Comprehensive test suite

Fixes #1430
