BUG: Empty variables on import.

[ShashwatXD]

Describe the bug/problem

When importing a cURL command via Dashbot, environment variables are automatically created (e.g., BASE_URL_XXX) but they appear as invisible/empty rows in the Variables page. The variable data exists and works correctly (hovering over URL fields shows the substituted value, API requests work), but the text fields in the Variables tab remain empty and don't display the key or value.

Steps to Reproduce the bug/problem

1. Open API Dash application
2. Navigate to Dashbot (chat interface)
3. Select "Import cURL" task
4. Paste a cURL command with a URL (e.g., curl https://api.example.com/users)
5. Click "Apply to Selected" or "Create New Request"
6. Navigate to the Environments section → Variables tab
7. Observe that a new row has been added (row count increases)
8. Notice that the text fields for the variable name and value are empty
9. Go back to the request and hover over the URL field → tooltip shows the variable is being substituted correctly (e.g., {{BASE_URL_API_EXAMPLE_COM}})
10. Send the API request → it works, confirming the variable has the correct value

Video: The Variables page shows an empty row where the imported variable should be visible with its key and value.

Expected behavior

When a variable is automatically created during cURL import, it should immediately appear in the Variables tab with:

• The variable key visible in the "Variable name" field (e.g., BASE_URL_API_EXAMPLE_COM)
• The variable value visible in the "Variable value" field (e.g., https://api.example.com)
• The checkbox showing the enabled state
