fix: add prompts/templates to backup + STDIO attach for docker-image servers

Two bugs fixed:

1. Backup completeness: JSON backup API now includes prompts and
   templates. Previously these were silently dropped during
   backup/restore, causing data loss on migration.

2. STDIO proxy for docker-image servers: servers with dockerImage
   but no packageName/command (like docmost) now use k8s Attach
   to connect to the container's PID 1 stdin/stdout instead of
   exec. This fixes "has no packageName or command" errors.

Changes:
- backup-service.ts: add BackupPrompt/BackupTemplate types, export them
- restore-service.ts: restore prompts (with project FK) and templates
- mcp-proxy-service.ts: sendViaPersistentAttach for docker-image STDIO
- orchestrator.ts: add attachInteractive to McpOrchestrator interface
- kubernetes-orchestrator.ts: implement attachInteractive via k8s Attach
- k8s-client-official.ts: expose Attach client
