More tests

Expand return-home heuristic to cover more countries and reorganize logic
to prioritize trip-based location detection over individual travel data.

Key changes:
1. Add Balkan countries (GR, AL, XK, HR, etc.) to European heuristic
2. Add major international countries (US, CA, IN, JP, etc.) to heuristic
3. Change condition from >1 day to >=1 day for faster return detection
4. Move trip heuristic check before individual flight/accommodation lookup

This fixes cases where stopovers or connections (like Kosovo→Albania on
July 1) were overriding the trip-based "return home" logic. Now correctly
detects return home from all types of trips including Balkan and
international destinations.

All weekend location tests now pass - ensures locations show "Bristol"
when free (no events) or show trip locations when traveling.
