The batch action (stop/start/restart) was being lost because:
1. Parse Callback Data extracted action: "stop"
2. Prepare Batch UI Input overwrote it with action: "exec" (the UI action type)
3. Handle Exec tried to parse callbackData which was empty
Fixed by:
- Adding batchAction field to Prepare Batch UI Input
- Adding batchAction to Batch UI trigger schema
- Updating Handle Exec to use triggerData.batchAction and selectedCsv

- Handles batch selection UI: mode, toggle, nav, clear, cancel, exec actions
- Returns structured data for main workflow to send Telegram responses
- Entry point: Execute Workflow Trigger with input contract
