fix(web): Preserve API error messages in config save handlers (#151)

Browse Source 
- Refactor error handling to use async/await for clearer flow
- Store response status before JSON parsing to preserve context
- Extract specific error messages from API responses (data.message)
- Only use generic HTTP status messages when JSON parsing fails
- Ensure API error messages like validation failures are shown to users
  instead of generic 'HTTP 500: Internal Server Error'

Fixes issue where specific API error messages were being replaced
with generic HTTP status messages in the catch handler.
