[TASK] Update display of "DB check" > "Full search"

To improve accessibility, labels have been added to various form fields
in the "Full search" area. In this process, existing hard-coded label
texts were moved to the corresponding XLF file and their names were
partially updated.

In the results list, all action buttons now have a link title.

Form fields that previously ran across the entire screen width were
limited in width to improve readability.
