A summary of the changes CodeRabbit can apply:

• Update src/lib/components/TaskTables/TaskTable.svelte to modify handleUpdateTaskResult so it iterates all task results and updates every instance with the same task_id (preserving contest_id, task_table_index, title), and updates taskResultsMap and the taskResults array to ensure Svelte reactivity and real-time synchronization of answer status across contests.

• Update src/lib/components/TaskTables/TaskTable.svelte by replacing handleUpdateTaskResult() so it iterates all taskResults and, for every entry with the same task_id, updates status fields (status_id, status_name, is_ac, updated_at) in both taskResultsMap and the taskResults array while preserving contest-specific fields (contest_id, task_table_index, title) to synchronize answer status across contests in real-time.
