feat(ui): replace mobile tab strip with custom full-width nav bar

Browse Source 
Avalonia's TabStrip ignores HorizontalAlignment overrides when placed at
Bottom, causing the items to cluster left. Replace it with a dedicated
Grid (ColumnDefinitions="*,*,*,*,*") that guarantees 5 equal columns
across the full width. The built-in TabStrip is hidden on mobile; buttons
in the custom bar call SelectTabCommand to drive SelectedTabIndex on the
TabControl.
