Isolate server search from the delete password prompt

The delete confirmation adds a password field. Browsers and password managers
paired it with the only other text field on the page and filled the account
name into the server search box on the server list.

The search input now stays out of the DOM while a delete confirmation is open,
and the toolbar shows a suspended notice styled to match the field it replaces
so the row does not jump. A jsdom test drives the real action menu and dialog
instead of asserting page source strings.
