feat: import places from Google Maps URLs — closes #141

Paste a Google Maps URL into the place search bar to automatically
import name, coordinates, and address. No API key required.

Supported URL formats:
- Short URLs: maps.app.goo.gl/..., goo.gl/maps/...
- Full URLs: google.com/maps/place/.../@lat,lng
- Data params: !3dlat!4dlng embedded coordinates

Server resolves short URL redirects and extracts coordinates.
Reverse geocoding via Nominatim provides name and address.
