/**
* BottomTabBar — fixed-bottom navigation for phone (≤767px).
*
* UI-SPEC §BottomTabBar:
* - Fixed bottom, full-width, 56px + env(safe-area-inset-bottom)
* - Background: var(--color-surface-dim)
* - Border-top: 1px solid var(--color-border)
* - Two equal tabs: Calendar (CalendarDays icon) and Lists (List icon)
* - Active tab: icon + label in var(--color-member-0), 2px border-bottom indicator
* - Inactive tab: icon + label in var(--color-text-muted)
* - Touch target: min 44px guaranteed by 56px bar height
* - z-index: 200 (below dialogs at 300)
*
* Uses react-router NavLink for real-URL active detection (D-17).
* Only rendered on phone (≤767px) — DesktopNav handles desktop navigation.
* Returns null on desktop so it does not overlay the AppNav sidebar avatar/Settings
* button (FIX 4). Same breakpoint (767px) as AppNav's phone/desktop switch.
