Filings UI: Invalid Spaces Error not Preventing COA Form Submission

[meawong]

How to Reproduce:

1. Start a COA filing.
2. Add invalid leading/trailing spaces in the required address fields.
3. Observe that validation raises invalid spaces error as expected.
4. Observe that the Update Addresses button is still enabled (should be disabled).
5. Click the Update Addresses button and see the added spaces are not reflected on the screen.
6. Submit the filing and observe that the leading/trailing spaces are submitted to the API.
