Adds CarPlay dashboard support (live map in the dashboard tile, arrow
centering and car visual scale) and the scene/app-lifecycle plumbing it
needs: showing the map without a connected phone scene, keeping the map
running while the phone is locked, maintaining a GPS fix, following the
position on cold launch into the car screen, and driving the app
lifecycle from aggregate UIApplication notifications via a single-layer
lifecycle observer.

The car inherited whatever zoom level the phone was at (drape preserves
meters-per-pixel across host switches), which reads too close on a car
screen and especially in the small dashboard tile. Zoom out to level 15
once per CarPlay session, when the map first follows the position on a
car screen and no route is active, leaving navigation auto-zoom and
manual zooming alone.
Adds FrameworkHelper.setZoomLevel using relative scaling, which unlike
SetViewportCenter keeps the location follow mode intact.

UpdateDependentParameters only rebuilt the 3D projection matrices when the
perspective angle moved by more than kEps. At angle 0 SetRotationAngle builds a
singular projection whose inverse (m_3dtoP) is NaN/Inf; that is only safe while
m_isPerspective is false. If perspective turned on for a sub-kEps angle, the
delta check skipped the rebuild and left the NaN matrix active, corrupting
P3dtoP/PtoP3d and through them m_Org -> a NaN screen rect that trips the
m2::Rect min<=max assert (rect2d.hpp:45).
Rebuild whenever m_isPerspective flips, not just when the angle delta exceeds
kEps.

Stress-testing CarPlay (rapid CarPlay<->phone switching, stop nav on the phone,
then re-open the CoMaps CarPlay icon) reproducibly aborted the debug build:
 m2::Rect<double>::Rect(...) ASSERT(minX<=maxX && minY<=maxY) rect2d.hpp:45
 +[MWMFrameworkHelper setVisibleViewport:scaleFactor:]
 CarPlayMapViewController.updateVisibleViewPortToNavigationState()
 CarPlayMapViewController.viewDidLayoutSubviews()
 -[CPWindow updateLayoutGuideWithInsets:] (layout-guide inset animation)
During the layout-guide animation / scene handoff the inset rect is transiently
degenerate or non-finite, so setVisibleViewport built an invalid m2::RectD whose
min<=max assert aborted the app (and would silently corrupt the viewport in
release).
setVisibleViewport now validates its input before constructing the rect: it
returns early unless scale is finite and > 0 and all four computed coordinates
are finite with x1 > x0 and y1 > y0. This guards every caller, not just CarPlay.
CarPlayMapViewController.updateVisibleViewPort additionally drops the frame up
front when the origin/size are not finite or the content scale factor is not
finite/positive; the previous width/height>0 check let a NaN origin through.

The CarPlay position-mode map button was built with a default glyph and
relied on callers to sync its icon to the actual mode afterwards. Several
template paths never did, so the button showed a stale icon — most visibly
when changing follow/follow-and-rotate on the phone and returning to a car
screen, but also on trip cancel and when starting navigation.
Build the button from a single source of truth (current position mode) in
buildMyPositionModeButton(), used by both base and navigation UI, so every
template path is correct by construction. Re-sync the live button on
re-host (dashboard/app switch) where no rebuild happens.
