Config UI: Vector Store Ids not stored for config

[Prajna1999]

Describe the bug
Config creation UI does not store the vector store ids even when they are added to the tools.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Configuration'
2. Click on 'Prompt Editor'
3. Go to 'Confiuguration' pane
4. Add a vector store id to the tools.

Expected behavior
Vector stores also to be stored with each configuration creation.

Additional context
Looks like the vector store nested structure was not spreading to match typescript keys and thereby messing the API contract
