Fix CSV import to actually work in UI with real functionality

CRITICAL FIXES FOR ACTUAL USER-FACING FUNCTIONALITY:

1. CELERY TASK DATABASE COMMITS:
- Fixed Celery task not committing database changes
- Imports now actually save to database instead of showing phantom statistics
- Added explicit db.session.commit() after import processing

2. DUPLICATE HANDLING STRATEGY UI:
- Added duplicate strategy dropdown to all CSV import forms
- Options: Merge (default), Replace, Skip
- Strategy properly passed through to services
- Works for campaign imports, general imports, and PropertyRadar

3. PROGRESS TRACKING FIXES:
- Progress now based on CSV rows, not contact counts
- Fixed percentage calculation (was showing 100% immediately)
- Progress updates incrementally during import
- Never exceeds 100%

4. STATISTICS ACCURACY:
- Fixed PropertyRadar statistics to show actual operations
- First import: Shows X created, 0 updated
- Second import: Shows proper created/updated/skipped based on strategy
- No more static '1788 imported, 1729 updated' every time

5. PROPERTYRADAR SERVICE INTEGRATION:
- Celery task now properly uses PropertyRadar service for PR CSVs
- Added campaign list repositories to service instantiation
- Fixed Result object handling (is_success property vs method)

FILES MODIFIED:
- routes/campaigns.py - Added duplicate_strategy parameter
- routes/main_routes.py - Added duplicate_strategy handling
- services/csv_import_service.py - Fixed async processing, added strategies
- services/propertyradar_import_service.py - Fixed statistics calculation
- tasks/csv_import_tasks.py - Fixed DB commits, progress tracking
- templates/*.html - Added duplicate strategy dropdowns
- tests/unit/services/test_csv_import_duplicate_strategies.py - New tests

The CSV import now actually works as expected in the UI with:
- Real progress tracking
- Accurate statistics
- Duplicate handling options
- Proper database persistence
- List associations that work
