## PR-Codex overview
This PR improves error handling in the `useCsvUpload` hook by adding a `try-catch` block around the CSV parsing logic. It ensures that if an error occurs during parsing or if the parsed data lacks an address, the component sets an error state and logs the error.

### Detailed summary
- Introduced a `try-catch` block around the CSV parsing logic.
- Added error handling to set `noCsv` to `true` if the parsed data's first entry does not have an `address`.
- Ensured that any errors during parsing are logged to the console.
