MoreCast User Feedback: Error submitting forecasts to WF1

Sentry Feedback: [FRONTEND-3T](https://bcps-wps.sentry.io/feedback/?referrer=github_integration&feedbackSlug=frontend%3A7479498627&project=4507138123890688)

I try to give this tool a go at least a few times per season. I seem to have bad luck with it... See error message below.
Thanks,

Error submitting forecasts to WF1, please retry. All your forecast inputs have been saved as a draft on your browser and can be submitted at a later time. If the problem persists, use the following link to verify the status of the WF1 service: https://wfapps.nrs.gov.bc.ca/pub/wfwx-fireweather-web/stations

Start with the linked Sentry Feedback report and reproduce the forecast submission failure against the WF1 service, using the provided service-status link for context. Done means identifying why submission fails, correcting the frontend behavior, and verifying that forecasts can be submitted successfully rather than only saved as browser drafts.
