Remove Theme.Material3.DynamicColors.DayNight from the notification
container style; it does not resolve correctly in the notification host
process, causing light-mode colors to appear in dark mode. Replace all
?attr/colorAccent and ?android:attr/textColorPrimary refs in RemoteViews
layouts with explicit day/night color resources (notification_icon_tint)
and TextAppearance.Compat.Notification.Title defaults. Change tintMode
from multiply to src_in for status glyphs; remove tint from product PNG
icons to prevent silhouette rendering.
Fixes#613
