Fix modal window small issues (elastic#238143)

## Summary

1. If workflow has manual trigger and defined inputs default tab in run
modal should be "Manual". Otherwise - "Alert"


https://github.com/user-attachments/assets/e3bd8151-f450-43a9-adbc-32be41a30dd5

2. Fix selection for alerts - it broke because of unsafe handling of
some nested objects "event.signal" on unflattening


https://github.com/user-attachments/assets/c65630d3-5068-4acf-a9c1-db161e0a38cc

3. Fix crush of Index tab. The reason was unsafe adding nested objects
as strings. Also mimic discovery style of displaying documents:
