- Added background task manager with goroutine execution and panic recovery - Replaced SSE streaming with background task execution for: * Price recalculation (RecalculateAll) * Stock import (ImportStockLog) * Pricelist creation (CreateWithProgress) - Implemented unified polling for task status and DB connection in frontend - Added task indicator in top bar showing running tasks count - Added toast notifications for task completion/error - Tasks automatically cleaned up after 10 minutes - Tasks show progress (0-100%) with descriptive messages - Updated handler constructors to receive task manager - Added API endpoints for task status (/api/tasks, /api/tasks/:id) Fixes issue with SSE disconnection on slow connections during long-running operations
