feat: Rebuild complete CSV import system for legacy data migration

PROBLEM SOLVED:
- Completely removed broken import functionality
- Built new robust, modular CSV import system from scratch
- Provides reliable data migration path for legacy .sc files

NEW IMPORT SYSTEM FEATURES:
✅ Modular CSV parsers for all 5 tables (ROLODEX, PHONE, FILES, LEDGER, QDROS)
✅ RESTful API endpoints with background processing (/api/admin/import/*)
✅ Admin web interface at /admin/import for file uploads
✅ Comprehensive validation and error handling
✅ Real-time progress tracking and status monitoring
✅ Detailed logging with import session tracking
✅ Transaction rollback on failures
✅ Batch import with dependency ordering
✅ Foreign key validation and duplicate detection

TECHNICAL IMPLEMENTATION:
- Clean /app/import_export/ module structure with base classes
- Enhanced logging system with import-specific logs
- Background task processing with FastAPI BackgroundTasks
- Auto-detection of CSV delimiters and encoding
- Field validation with proper data type conversion
- Admin authentication integration
- Console logging for debugging support

IMPORT WORKFLOW:
1. Admin selects table type and uploads CSV file
2. System validates headers and data structure
3. Background processing with real-time status updates
4. Detailed error reporting and success metrics
5. Import logs stored in logs/imports/ directory

SUPPORTED TABLES:
- ROLODEX (contacts/people) - 19 fields, requires: id, last
- PHONE (phone numbers) - 3 fields, requires: rolodex_id, phone
- FILES (case files) - 29 fields, requires: file_no, id, empl_num, file_type, opened, status, rate_per_hour
- LEDGER (transactions) - 12 fields, requires: file_no, date, t_code, t_type, empl_num, amount
- QDROS (documents) - 31 fields, requires: file_no

REMOVED FILES:
- app/api/unified_import_api.py
- app/services/unified_import.py
- app/api/flexible.py
- app/models/flexible.py
- templates/unified_import.html
- templates/flexible.html
- static/js/flexible.js
- All legacy import routes and references

TESTING COMPLETED:
✅ Schema validation for all table types
✅ CSV header validation
✅ Single file import functionality
✅ Multi-table dependency validation
✅ Error handling and logging
✅ API endpoint integration

READY FOR PRODUCTION: System tested and validated with sample data.
Administrators can now reliably import CSV files converted from legacy .sc files.
