feat: Add filters to Find Client widget

[rubenvdlinde]

Summary

• Add type (person/organization), address, and industry filter controls to the Find Client dashboard widget
• Replace simple text search with a full filter form — all filters combine with AND logic
• Industry dropdown is auto-populated from existing client data

Closes #175

Test plan

• Open the dashboard and verify the Find Client widget shows the filter form
• Filter by type (person/organization) and verify results narrow correctly
• Type in the address filter and verify partial matching works
• Select an industry and verify only matching clients show
• Combine multiple filters with text search and verify AND logic
