Merge upstream/main into fix/drone-airspace

Move the share-link token to 6 (3 is gnss-integrity), build altitude
ranges from LOWER/UPPER VAL, UOM and CODE, mark card and legend strings
for translation, rename the layer to Prohibited & Restricted Airspace,
move the changelog entry to changelog.d, and keep the layer voice-off
while the Realtime prompt is at its budget.
