Fix vuejs-accessibility/label-has-for violations: associate labels with form controls

Associate every <label> with its form control via explicit for/id pairs
or by wrapping the input inside the label element:

- DeviceSettingsPage, SelectFacilityPage, Init, SelectFacilityForm:
  add matching for/id attributes to disconnected label+input pairs
- PicturePasswordOption: add for/id wiring to the password option
  checkbox with a stable computed checkboxId
- QuestionDetailLearnerList: add for/id wiring to the attempt number
  input and simplify the focused-element ref
- SearchBox: wrap the search input inside its label element
