refactor(sort-orders): remove outdated deployment and implementation guides
- Deleted the `DEPLOYMENT_GUIDE_SORT_ORDERS.md` and `SEPARATE_SORT_ORDERS_IMPLEMENTATION.md` files as they are no longer relevant following the recent updates to the sort orders feature. - Introduced new migration scripts to address duplicate sort orders and ensure data integrity across the updated task sorting system. - Updated database schema to include new sort order columns and constraints for improved performance and organization. - Enhanced backend functions and frontend components to support the new sorting logic and maintain user experience during task organization.

-- 4. USAGE INSTRUCTIONS
|
||||
|
||||
/*
|
||||
USAGE:
|
||||
|
||||
1. First, run the detection queries to see which projects have duplicates
|
||||
2. Then run this to fix all duplicates:
|
||||
SELECT fix_all_duplicate_sort_orders();
|
||||
3. Finally, verify the fix worked:
|
||||
SELECT * FROM verify_sort_order_integrity();
|
||||
|
||||
If verification returns no rows, all duplicates have been fixed successfully.
|
||||
|
||||
WARNING: This will reassign sort order values based on current order + creation time.
|
||||
Make sure to backup your database before running these functions.
