fix: preserve XCom multi-column sorting

[auyua9]

Preserve multi-column XCom sorting across the table URL state and API request.

Summary:

• keep repeated sort search params when serializing table state
• map every XCom sorting entry into the API orderBy list
• keep the existing task_display_name to task_id mapping for each sort entry

Tests:

• ./node_modules/.bin/vitest run src/components/DataTable/searchParams.test.ts src/pages/XCom/orderBy.test.ts
• ./node_modules/.bin/eslint --quiet src/components/DataTable/searchParams.test.ts src/components/DataTable/searchParams.ts src/pages/XCom/XCom.tsx src/pages/XCom/orderBy.test.ts src/pages/XCom/orderBy.ts
• ./node_modules/.bin/tsc -p tsconfig.app.json --noEmit
• git diff --check

Thanks for the pr

Could you share a recording of the expected behavior and the current behavior?

I tested your code with Shift-click, but multiple column sorting still doesn't seem to work.
