fix: apply elevation color thresholds on radar page

LocalElevationThresholds was provided inside MainScreen, but RadarDestination
is a root-level sibling entry in NavRoot's NavDisplay, so the radar page's
top bar fell outside the CompositionLocal scope and always used the default
15/45 thresholds instead of the user-configured ones.

Hoist the CompositionLocalProvider to NavRoot so both the tab content and
the root-level RadarDestination read the user's low/high elevation
thresholds, and drop the now-redundant provider from MainScreen.
