v1.48.0

Changed

• Mobile-first frontend pass: crowded navigation now keeps four primary apps and moves the rest
  into an accessible More menu; audit entries, users, containers, Docker networks/volumes, SMB
  connections and mounts become cards instead of horizontally scrolling tables on phones.
• Accessible dialogs and feedback: dialogs behave as bottom sheets on mobile, trap keyboard
  focus, restore focus when closed and expose dialog semantics. Shared loading, error and empty
  states, clearer focus rings, touch feedback, accessible icon labels and live toast announcements
  make async operations more consistent across the interface.
• Data backup controls: rsync plans can now be edited, paused and re-enabled from Settings, with
  clearer execution-state badges and responsive action layouts.
• Frontend polish: form controls have clearer focus feedback, keyboard focus is consistent, and
  mobile cards, headers and action groups have more balanced spacing and touch-friendly layouts.

Fixed

• Reliable telemetry delivery: a heartbeat that fails while network or DNS is still coming up
  now retries after one hour instead of silently waiting a full day. The HTTPS timeout is increased
  to ten seconds, failures are logged without payload data, and this release forces one corrective
  heartbeat from existing installations.
• Mobile layout overflow: the bottom navigation now shares the available viewport width instead
  of extending the page, wide dashboard widgets collapse to one column on phones, and settings,
  storage, monitoring, sharing, App Store, audit and backup screens use responsive spacing and
  wrapping. The shell now follows the dynamic mobile viewport and respects safe-area insets.
