fix: fixed the weekly file table sorting issue

Description

Summary of Changes

1. Weekly Summary Table - Backend Sorting (Full Dataset)

Problem: Sorting Weekly File Date / CSA Processing Date only sorted the current page, not the entire list.

Solution:

• Frontend (WeeklyFileProcessingTab.tsx): Now passes sort parameter to getWeeklyFiles() API call and resets to page 1 when sort changes.
• Frontend service (weekly-files-service.ts): Added sort parameter support to getWeeklyFiles().
• Backend controller (weekly-files.controller.ts): Added sort query parameter to GET /weekly-files.
• Backend service (weekly-files.service.ts): Implemented server-side sorting before pagination for weeklyFileDate and csaProcessingDate.

2. Unified Sort Parser (Backend Refactor)

Problem: Two nearly identical sort parser functions existed for summary and details tables.

Solution: Created one generic function in weekly-files.service.ts:

function parseWeeklySort<T extends string>(
  sort: string | undefined,
  allowedColumns: readonly T[],
): { column: T; direction: 'asc' | 'desc' } | null

Both tables now use this single parser with their respective allowlists:

• Weekly Summary: ALLOWED_WEEKLY_SUMMARY_SORT_COLUMNS
• Weekly Details: ALLOWED_WEEKLY_RECORD_SORT_COLUMNS

Result

Table	Sorting Scope	Uses Unified Parser
Weekly Summary	Full dataset ✅	✅
Weekly Details	Full dataset ✅	✅
Child Search	Current page (unchanged)	N/A
