fix(web): map selected files to file-type params and hide auto-injected params

File/directory type app parameters now show the associated file name instead of
a disabled input. WORK_DIR is hidden from the form as it is auto-injected by the
backend. Selected files are mapped to file params via fileParamMapping on submit.
