feat(contact_form): Enable selection of issue type and enable Jira integration

[elisa-a-v]

Addresses #4585

This update enhances the contact form by allowing users to select the "Issue Type" for their submission, and also optionally pre-select it via URL query parameters, improving UX.

Additionally, the contact form now sends submissions to support@freelawproject.atlassian.net, integrating with Jira for better issue tracking. The email body includes:

• User Email: Displayed as User Email: <email address> to facilitate easy parsing in Jira.
• Issue Type: Clearly stated to assist in automatic categorization within Jira.
• Subject and Message: Retained as before for detailed context.

This change enables automatic ticket creation to relieve some of the overhead of managing requests manually by email.

@mlissner I had issues with the pre-commit when working on this which is why there are so many commits each doing very little, but I got it working now so it won't happen again!

I can revert them and add all the small changes in a single commit, please let me know if I should do it or just leave it as is.

Looks good to me at a glance. Off to Eduardo for more careful review. The commits are fine, we can just squash when we merge.

Thank you and congrats on your first (official) PR!

@s-taube, before we merge this, have you had a chance to look at the security vuln I mentioned that this might open up?

Yes. As far as I can tell, this Zendesk issue should not impact Atlassian products at all.

The code is looking great! Just a couple of small things to address before we can merge this PR.

LGTM

OK, here we go. Thanks everybody. @s-taube, in about ten minutes, when this finishes, this code will be live and I think we'll be in Jira-land.

Thanks all!
