Add anchors and redirect embeds to help preserve scroll position

Resolves #420

Workaround to help preserve scroll position while editing objects in combined show view/form.

• Add anchors to section headers
• Embed anchors in controller redirects for all appropriate actions
• In the controller specs, add checks for anchors in the redirects

The code is fine and works as expected. Unfortunately, when a user does not fill out all the fields for an in-house repair or external repair, the flash message indicating that the repair was not created is no longer visible. The user would need to scroll to the top of the record to view it. From the user's point of view, no notification occurs that a repair failed to save.

This maybe should be solved in a separate issue. Perhaps the pop-up for creating the repair could refuse to close if all the required fields aren't filled out?

It could be as simple as marking the items that are required as required: true to force their selection from within the modal.

I think we could set a conditional to reroute to top in case of validation failure. I'm intrigued about a js solution to the scrolling issue.

@Janell-Huyck Flagged the required fields. This should be ready to go.
