Fix: Fixes for accessibility after QA

[TheDancingClown]

📝 A short description of the changes

Some additional accessibility fixes after QA testing. After testing it was found the palace attendee forms had multiple errors for duplicated or missing labels. This was caused by generating two forms for javascript and non-javascript (where we needed multiple attendee in the past). Most errors are fixed by only prebuilding the palace_attendee once and adding an index to the labels, however this code has been commented out while we only need 1 palace attendee. We should look at moving this logic to the controller if the situation changes.

• Adds missing labels on admin and assessor application appraisal views
• Fixes alignment and hover styles for checkboxes in collaborator form
• Moves Reports heading to top of page
