a11y: missing labels on controls (text fields, select boxes)

Swagger UI renderer breaks accessibility rules: WCAG 1.3.1, WCAG 4.1.2

• path: http://localhost:1723
• also text fields, checkboxes etc

Fix ONE of the following:

• aria-label attribute does not exist or is empty
• aria-labelledby attribute does not exist, references elements that do not exist or references elements that are empty
• Form element does not have an implicit (wrapped)
• Form element does not have an explicit
• Element has no title attribute or the title attribute is empty

See screenshot: fields in RED are failing
