Fix TypeError in Bedesten search tools - add null safety checks

Resolves 'cannot convert undefined or null to object' error in search_bedesten_unified
by adding proper null checking for response.data.emsalKararList and response.data.total
fields before accessing them.

- Add hasattr() and null checks for response.data fields
- Provide safe defaults: empty list for emsalKararList, 0 for total
- Prevents TypeError when API returns undefined/null fields
- Matches null safety pattern used in other search tools
