Fix: Address E2E bugs from real-world MCP testing

Browse Source 
Fixes three critical bugs discovered during live testing with Claude:

Bug #1: Same building detection always returned 0
- Root cause: deal.get('address') returned empty string
- Fix: Construct address from streetNameHeb + houseNum fields
- Added test: test_same_building_detection_with_api_fields

Bug #2: Property type filter too strict
- Root cause: Exact match failed for variants like 'דירת גג'
- Fix: Use flexible substring matching with normalization

Bug #3: Deal deduplication used non-existent field
- Root cause: Deduplication key referenced deal.get('address')
- Fix: Removed non-existent field from deduplication key

Also added _calculate_distance() helper for future radius filtering.

Test results: 26/28 passing (2 pre-existing failures unrelated)
