fix(batch): resolve container IDs in sub-workflows

When batch operations are triggered via keyboard callbacks, the main
workflow only passes container names (not IDs). The sub-workflows now:
- Check if containerId is empty
- If empty, query Docker API to resolve name → ID
- Then proceed with the action

This fixes batch start/stop/restart/update operations failing with
404 "page not found" errors.
