Remove billedTo filtering to show all bills to landlord

The billedTo field indicates payment responsibility (tenant vs landlord),
not viewing permissions. Landlords should see and manage ALL bills.

Changes:
- LocationCard: Display all bills regardless of billedTo value
- LocationCard: Calculate monthlyExpense from all paid bills
- HomePage: Include all paid bills in monthlyExpense aggregation
- printActions: Print all bills with barcodes regardless of billedTo
- locationActions: Add billedTo property to fetchAllLocations result
