fix: migrate Places and Routes to new GCP APIs

Switch from legacy Places textsearch and Directions APIs (disabled on
this project) to Places API (New) and Routes API (New). Both places.py
and the assistant's _places_search helper updated. Also fixes uid()
recursive self-call in trips page and adds Places API response logging.
