v0.321.0: FileBrowser's stale password and its own banners; one backup section on the Data tab; install address of an installed app

R-1101: the change-it line is gone for FileBrowser; in the generated state the page asks FileBrowser whether
the stored password still logs in (only its own 401/403 counts) and, refused, says so and offers the
new-password press. The rendered FileBrowser config switches off its update notice and its Install-app
prompt. The Data tab's backup part is one section in plain words (no off-drive, no PBS); the export
password eye is a text button. R-1095: /apps/{slug}/install of an installed app 302s to its settings tab.
