GpsService runs a single-shot position request with a hard timeout
and early-exit when Config.GPS_TARGET_ACCURACY_M is reached.
LoadingView renders a circular progress bar around the edge plus the
"Standort wird bestimmt" prompt; on callback it persists a new Event
via EventStore.add and transitions to SuccessView (green checkmark,
short vibration, auto-close) or ErrorView (red alert, 3× vibration,
German message, longer hold). TextUtils extracts the shared
multi-line centered text rendering so MenuView, LoadingView and
ErrorView all render wrapped German text consistently. Positioning
permission added to manifest.
