New web UI with iPhone web app

Redesigned status, log, tag generator and settings pages: spool rings in
filament colour, live job card (progress and time left read from CC2
Control's /api/printer while a job runs), log page with filters, iOS-style
settings with a write/dry-run switch. On phones: bottom tab bar, printer
switcher, slot details in a bottom sheet. Dark mode follows the system.
Web app manifest and home screen icons for "Add to Home Screen".
